Lodash _.isSafeInteger() Method
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.
javascript
// 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.
javascript
// 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.
