Lodash _.isSafeInteger() method is used to find whether the given value is a safe integer or not. It returns True if the given value is a safe integer. Otherwise, it returns false. An integer is safe if it's an IEEE-754 double-precision number(all integers from (2 53 - 1) to -(2 53 - 1)) which isn't the result of a rounded unsafe integer.
Syntax:
_.isSafeInteger(value);Parameters:
- value: This parameter holds the value to check.
Return Value:
- This method returns true if the value is a safe integer, else false.
Example 1: In this example, we are checking whether the given value is a safe integer or not.
// Requiring lodash library
const _ = require('lodash');
// Use of _.isSafeInteger() method
// Passing a mathematical pow function as an argument
console.log(_.isSafeInteger(Math.pow(2, 53) - 1));
// Passing a maximum value of a number as an argument
console.log(_.isSafeInteger(Infinity));
// Passing a minimum value of a number as an argument
console.log(_.isSafeInteger(Number.MIN_VALUE));
Output:
true
false
false
Example 2: In this example, we are checking whether the given value is a safe integer or not.
// Requiring lodash library
const _ = require('lodash');
// Use of _.isSafeInteger() method
// Passing a positive number as an argument
console.log(_.isSafeInteger(123));
// Passing a negative number as an argument
console.log(_.isSafeInteger(-123));
// Passing a number(with decimals) as an argument
console.log(_.isSafeInteger(0.123));
Output:
true
true
false
Note: This code will not work in normal JavaScript because it requires the library lodash to be installed.
