toFloat32

Convert a double-precision floating-point number to the nearest single-precision floating-point number.

Usage

var float64ToFloat32 = require( '@stdlib/number/float64/base/to-float32' );

float64ToFloat32( x )

Converts a double-precision floating-point number to the nearest single-precision floating-point number.

var y = float64ToFloat32( 1.337 );
// returns 1.3370000123977661

Notes

• This function may be used as a polyfill for the ES2015 built-in Math.fround.

Examples

var randu = require( '@stdlib/random/base/randu' );
var float64ToFloat32 = require( '@stdlib/number/float64/base/to-float32' );

var f64;
var f32;
var i;

// Convert random double-precision floating-point numbers to the nearest single-precision floating-point number...
for ( i = 0; i < 1000; i++ ) {
    f64 = randu() * 100.0;
    f32 = float64ToFloat32( f64 );
    console.log( 'float64: %d => float32: %d', f64, f32 );
