Pace (unit)

A pace is a unit of length consisting either of one normal walking step (~0.75 m), or of a double step, returning to the same foot (~1.5 m). Like other traditional measurements, paces started as informal units but have since been standardized, often with the specific length set according to a typical brisk or military marching stride.

In the US, it is an uncommon customary unit of length denoting a brisk single step and equal to 2½ feet or 30 inches (76.2 cm).

The term "pace" is also used to translate similar formal units in other systems of measurement. Pacing is also used as an informal measure in surveying, with the "pace" equal to two of the surveyor's steps reckoned through comparison with a standard rod or chain.

Other systems

The Roman pace (Latin: passus) was a Roman unit of length. It was notionally the distance of a full stride from the position of one heel where it raised off of the ground to where it set down again at the end of the step: two steps, one by each foot. Under Marcus Vipsanius Agrippa, it was standardized as the distance of two steps (gradūs) or five Roman feet (pedes), about 1.48 meters or 4 feet 10 inches. There were 1000 paces in the Roman mile, which was named after that distance as the mille passus or passuum.

C data types

In the C programming language, data types are declarations for memory locations or variables that determine the characteristics of the data that may be stored and the methods (operations) of processing that are permitted involving them.

The C language provides basic arithmetic types, such as integer and real number types, and syntax to build array and compound types. Several header files in the C standard library contain definitions of support types, that have additional properties, such as providing storage with an exact size, independent of the implementation.

Basic types

The C language provides the four basic arithmetic type specifiers char, int, float and double, and the modifiers signed, unsigned, short and long. The following table lists the permissible combinations to specify a large set of storage size-specific declarations.

The actual size of integer types varies by implementation. The standard only requires size relations between the data types and minimum sizes for each data type:

Double-precision floating-point format

Double-precision floating-point format is a computer number format that occupies 8 bytes (64 bits) in computer memory and represents a wide, dynamic range of values by using a floating point.

Double-precision floating-point format usually refers to binary64, as specified by the IEEE 754 standard, not to the 64-bit decimal format decimal64.

IEEE 754 double-precision binary floating-point format: binary64

Double-precision binary floating-point is a commonly used format on PCs, due to its wider range over single-precision floating point, in spite of its performance and bandwidth cost. As with single-precision floating-point format, it lacks precision on integer numbers when compared with an integer format of the same size. It is commonly known simply as double. The IEEE 754 standard specifies a binary64 as having:

This gives 15–17 significant decimal digits precision. If a decimal string with at most 15 significant digits is converted to IEEE 754 double precision representation and then converted back to a string with the same number of significant digits, then the final string should match the original. If an IEEE 754 double precision is converted to a decimal string with at least 17 significant digits and then converted back to double, then the final number must match the original.

The Double (Gaelic games)

The Double is a term in Gaelic games that refers to a county winning the All-Ireland Senior Football Championship and the All-Ireland Senior Hurling Championship in the same year. Other major trophies won in combination in the same year at minor or under-21 levels are also often referred to as doubles. Similarly, the winning of the All-Ireland and the National League titles in the same year may also be referred to as the Double, albeit an inferior one.

The Double

Only two counties have achieved this rare distinction at Senior level, both on two separate occasions:

National League-All-Ireland double

This is a much more common double.

Near Doubles

A great many sides over the years have come close to winning the coveted senior double but narrowly failed to do so by losing one or both of the championships at the end of the season.

Horse gait

Horse gaits are the various ways in which a horse can move, either naturally or as a result of specialized training by humans.

Classification

Gaits are typically categorized into two groups: the "natural" gaits that most horses will use without special training, and the "ambling" gaits that are various smooth-riding four-beat footfall patterns that may appear naturally in some individuals, but which usually occur only in certain breeds. Special training is often required before a horse will perform an ambling gait in respond to a rider's command.

Another system of classification that applies to quadrupeds uses three categories: walking and ambling gaits, running or trotting gaits, and leaping gaits.

The British Horse Society Dressage Rules require competitors to perform four variations of the walk, six forms of the trot, five leaping gaits (all forms of the canter), halt, and rein back, but not the gallop. The British Horse Society Equitation examinations also require proficiency in the gallop as distinct from the canter.

Pace (transit)

Pace is the suburban bus division of the Regional Transportation Authority in the Chicago metropolitan area. It was created in 1983 by the RTA Act, which established the formula that provides funding to CTA, Metra and Pace. In 2013, Pace had 39.925 million riders.

Pace's headquarters are in Arlington Heights, Illinois. Pace is governed by a 13 member Board of Directors, 12 of which are current and former suburban mayors, with the other being the Commissioner of the [Chicago] Mayor's Office for People with Disabilities, to represent the city's paratransit riders.

The six counties that Pace serves are Cook, Lake, Will, Kane, McHenry and DuPage. Some of Pace's buses also go to Chicago and Indiana. In some areas, notably Evanston, River Forest, Oak Park, and Skokie, Pace and Chicago Transit Authority (CTA) both serve the community.

Many of Pace's hubs are located at CTA rail stations (especially terminals) and Metra stations. CTA and Pace have shared a payment system since 2014 called Ventra. Ventra accounts are required to obtain transfers. Metra fares are completely separate, but a phone app is being developed that may allow Metra payment with Ventra.
