Octal
The octal numeral system, or oct for short, is the base-8 number system, and uses the digits 0 to 7. Octal numerals can be made from binary numerals by grouping consecutive binary digits into groups of three (starting from the right). For example, the binary representation for decimal 74 is 1001010, which can be grouped into (00)1 001 010 – so the octal representation is 112.
In the decimal system each decimal place is a power of ten. For example:
In the octal system each place is a power of eight. For example:
By performing the calculation above in the familiar decimal system we see why 112 in octal is equal to 64+8+2 = 74 in decimal.

Água De Lua
by: DjavanFaca de ponta, peixeira
Pau na moleira, espingarda
Cano comprido estampido no ar
Clarão da espada afiada
A morte um dia há de chegar
Fogo cuspiu, labareda
Flora no mato, vereda
Prata boiando nas águas do luar
Clarão da espada afiada
A morte um dia há de chegar
Eu me criei no molhado
Areia e pedras do lado
Berço de uma sereia
