    Cube Root

    NPM version Build Status Coverage Status dependencies

    Compute the cube root of a single-precision floating-point number.

    Installation

    npm install @stdlib/math-base-special-cbrtf

    Usage

    var cbrtf = require( '@stdlib/math-base-special-cbrtf' );

    cbrtf( x )

    Computes the cube root of a single-precision floating-point number.

    var v = cbrtf( 64.0 );
    // returns 4.0
    
    v = cbrtf( 27.0 );
    // returns 3.0
    
    v = cbrtf( 0.0 );
    // returns 0.0
    
    v = cbrtf( -0.0 );
    // returns -0.0
    
    v = cbrtf( -9.0 );
    // returns ~-2.08
    
    v = cbrtf( NaN );
    // returns NaN

    Examples

    var randu = require( '@stdlib/random-base-randu' );
    var cbrtf = require( '@stdlib/math-base-special-cbrtf' );
    
    var x;
    var i;
    
    for ( i = 0; i < 100; i++ ) {
        x = (randu()*200.0) - 100.0;
        console.log( 'cbrt(%d) = %d', x, cbrtf( x ) );
    }

    C APIs

    Installation

    npm install @stdlib/math-base-special-cbrtf

    Usage

    #include "stdlib/math/base/special/cbrtf.h"

    stdlib_base_cbrtf( x )

    Computes the cube root of a single-precision floating-point number.

    float y = stdlib_base_cbrtf( 27.0f );
    // returns 3.0f

    The function accepts the following arguments:

    • x: [in] float input value.
    float stdlib_base_cbrtf( const float x );

    Examples

    #include "stdlib/math/base/special/cbrtf.h"
    #include <stdio.h>
    
    int main() {
        float x[] = { 3.14f, 9.00f, 0.0f, 0.0f/0.0f };
    
        float y;
        int i;
        for ( i = 0; i < 4; i++ ) {
            y = stdlib_base_cbrtf( x[ i ] );
            printf( "cbrt(%f) = %f\n", x[ i ], y );
        }
    }

    Notice

    This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
