Node.js util.types.isFloat32Array() Method
The util.types.isFloat32Array() method is an inbuilt application programming interface of the util module which is used to type check for Float32Array in the node.js.
Syntax:
util.types.isFloat32Array( value )
Parameters: This method accepts a single parameter as mentioned above and described below.
- value: It is a required parameter of any datatype.
Return: This returns a boolean value, TRUE if the value is a Float32Array, FALSE otherwise.
The below examples illustrate the use of util.types.isFloat32Array() method in Node.js:
Example 1:
javascript
// Node.js program to demonstrate the // util.types.isFloat32Array() Method // Allocating util module const util = require( 'util' ); // Value to be passed as parameter of // util.types.isFloat32Array() method let v1 = new BigInt64Array(); let v2 = new BigUint64Array(); let v3 = new Float32Array(); let v4 = new ArrayBuffer(); let v5 = new Float64Array(); // Printing the returned value from // util.types.isFloat32Array() method console.log(util.types.isFloat32Array(v1)); console.log(util.types.isFloat32Array(v2)); console.log(util.types.isFloat32Array(v3)); console.log(util.types.isFloat32Array(v4)); console.log(util.types.isFloat32Array(v5)); |
Output:
false false true false false
Example 2:
javascript
// Node.js program to demonstrate the // util.types.isFloat32Array() Method // Allocating util module const util = require( 'util' ); // Value to be passed as parameter of // util.types.isFloat32Array() method let v1 = new Float32Array(); let v2 = new Float32Array(); // Calling util.types.isFloat32Array() method if (util.types.isFloat32Array(v1)) console.log( "The passed value is a Float32Array." ); else console.log( "The passed value is not a Float32Array" ); if (util.types.isFloat32Array(v2)) console.log( "The passed value is a Float32Array." ); else console.log( "The passed value is not a Float32Array" ); |
Output:
The passed value is a Float32Array. The passed value is not a Float32Array
Note: The above program will compile and run by using the node filename.js command.
