    Cube Root

    NPM version Build Status Coverage Status dependencies

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

    Installation

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

    Usage

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

    cbrt( x )

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

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

    Examples

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

    Installation

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

    Usage

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

    stdlib_base_cbrt( x )

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

    double y = stdlib_base_cbrt( 27.0 );
    // returns 3.0

    The function accepts the following arguments:

    • x: [in] double input value.
    double stdlib_base_cbrt( const double x );

    Examples

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