is-safe-integer-x

Determine whether the passed value is a safe integer.

module.exports(value) ⇒ boolean ⏏

This method determines whether the passed value is a safe integer.

Can be exactly represented as an IEEE-754 double precision number, and whose IEEE-754 representation cannot be the result of rounding any other integer to fit the IEEE-754 representation.

Kind: Exported function
Returns: boolean - A Boolean indicating whether or not the given value is a safe integer.

Param	Type	Description
value	*	The value to be tested for being a safe integer.

Example

import isSafeInteger from 'is-safe-integer-x';
 
console.log(isSafeInteger(0)); // true
console.log(isSafeInteger(1)); // true
console.log(isSafeInteger(-100000)); // true
 
console.log(isSafeInteger(Math.pow(2, 53))); // false
console.log(isSafeInteger(0.1)); // false
console.log(isSafeInteger(Math.PI)); // false
 
console.log(isSafeInteger(NaN)); // false
console.log(isSafeInteger(Infinity)); // false
console.log(isSafeInteger(-Infinity)); // false
console.log(isSafeInteger('10')); // false
console.log(isSafeInteger(true)); // false
console.log(isSafeInteger(false)); // false
console.log(isSafeInteger([1])); // false
