Underscore.js _.isFloat() Method
The _.isFloat() method checks whether the given value is a Float value or not, and returns the corresponding boolean value.
Syntax:
_.isFloat( value );
Parameters:
- value: Given value to be checked for Float value.
Return Value: This method returns a Boolean value(Returns true if the given value is even, else false).
Note: This will not work in normal JavaScript because it requires the underscore.js contrib library to be installed. Underscore.js contrib library can be installed using npm install underscore-contrib .
Example 1:
Javascript
var _ = require( 'underscore-contrib' );
console.log( "The Value is Float : "
+ _.isFloat(4.91));
|
Output:
The Value is Float : true
Example 2:
Javascript
var _ = require( 'underscore-contrib' );
console.log( "The Value is Float : "
+ _.isFloat(21));
|
Output:
The Value is Float : false
Example 3: For this method values 2.0 and 2 both will be considered as an integer, so this method will return false.
Javascript
var _ = require( 'underscore-contrib' );
console.log( "The Value is Float : "
+ _.isFloat(2.0));
|
Output:
The Value is Float : false
Example 4: A string containing float value will return true.
Javascript
var _ = require( 'underscore-contrib' );
console.log( "The Value is Float : "
+ _.isFloat( "2.188" ));
|
Output:
The Value is Float : true
