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

var isSafeInteger = require('is-safe-integer-x');

isSafeInteger(0);                    // true
isSafeInteger(1);                    // true
isSafeInteger(-100000);              // true

isSafeInteger(Math.pow(2, 53));      // false
isSafeInteger(0.1);                  // false
isSafeInteger(Math.PI);              // false

isSafeInteger(NaN);                  // false
isSafeInteger(Infinity);             // false
isSafeInteger(-Infinity);            // false
isSafeInteger('10');                 // false
isSafeInteger(true);                 // false
isSafeInteger(false);                // false
isSafeInteger([1]);                  // false
