Javascript - Arithmetic in Javascript

JavaScript supports basic arithmetic operations like addition, subtraction, multiplication, and division using operators like +, -, *, and /. It also supports more complex math through functions in the Math object. When numeric operations result in overflow, underflow, or division by zero, JavaScript does not produce errors - it returns special values like Infinity, -Infinity, 0, or NaN instead of errors.
Javascript - Arithmetic in Javascript
- 1. Arithmetic in JavaScript Mathematical operations
- 2. Arithmetic in JavaScript • JavaScript programs work with numbers using the arithmetic operators that the language provides.
- 3. Arithmetic in JavaScript • + for addition, • - for subtraction, • * for multiplication, • / for division, • and % for modulo.
- 4. Arithmetic in JavaScript • + for addition, • - for subtraction, • * for multiplication, • / for division, • and % for modulo.
- 5. Arithmetic in JavaScript • JavaScript supports more complex mathematical operations through a set of functions and constants defined as properties of the Math object.
- 7. Arithmetic in JavaScript • Arithmetic in JavaScript does not raise errors in cases of overflow, underflow, or division by zero.
- 8. Arithmetic in JavaScript • When the result of a numeric operation is larger than the largest representable number (overflow), the result is a special infinity value, which JavaScript prints as Infinity.
- 9. Arithmetic in JavaScript • when a negative value becomes larger than the largest representable negative number, the result is negative infinity, printed as -Infinity.
- 10. Arithmetic in JavaScript • When a negative value becomes larger than the largest representable negative number, the result is negative infinity, printed as -Infinity.
- 11. Arithmetic in JavaScript • Underflow occurs when the result of a numeric operation is closer to zero than the smallest representable number. • In this case, JavaScript returns 0.
- 12. Arithmetic in JavaScript • If underflow occurs from a negative number, • JavaScript returns a special value known as “negative zero.”
- 13. Arithmetic in JavaScript • Division by zero is not an error in JavaScript: it simply returns infinity or negative infinity. • 0/0 is not Infinity • There is one exception!!
- 14. Arithmetic in JavaScript • zero divided by zero does not have a well defined value, and the result of this operation is the special not-a- number value, printed as NaN. • 0/0 = NaN
- 15. Arithmetic in JavaScript • NaN also arises if you attempt to divide infinity by infinity. • take the square root of a negative number (NaN).
