Reciprocal Cube Root
Compute the reciprocal of the principal cube root of a double-precision floating-point number.
The reciprocal of the principal cube root is defined as
Installation
npm install @stdlib/math-base-special-rcbrt
Usage
var rcbrt = require( '@stdlib/math-base-special-rcbrt' );
rcbrt( x )
Computes the reciprocal (inverse) cube root of a double-precision floating-point number.
var v = rcbrt( 1.0 );
// returns 1.0
v = rcbrt( 8.0 );
// returns 0.5
v = rcbrt( 1000.0 );
// returns 0.1
v = rcbrt( 0.0 );
// returns Infinity
v = rcbrt( NaN );
// returns NaN
v = rcbrt( Infinity );
// returns 0.0
Examples
var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var rcbrt = require( '@stdlib/math-base-special-rcbrt' );
var x;
var i;
for ( i = 0; i < 100; i++ ) {
x = round( randu() * 100.0 );
console.log( 'rcbrt(%d) = %d', x, rcbrt( x ) );
}
C APIs
Usage
#include "stdlib/math/base/special/rcbrt.h"
stdlib_base_rcbrt( x )
Computes the reciprocal (inverse) cube root of a double-precision floating-point number.
double y = stdlib_base_rcbrt( 8.0 );
// returns 0.5
The function accepts the following arguments:
- x:
[in] double
input value.
double stdlib_base_rcbrt( const double x );
Examples
#include "stdlib/math/base/special/rcbrt.h"
#include <stdio.h>
int main( void ) {
const double x[] = { 3.14, 9.0, 0.0, 0.0/0.0 };
double y;
int i;
for ( i = 0; i < 4; i++ ) {
y = stdlib_base_rcbrt( x[ i ] );
printf( "rcbrt(%lf) = %lf\n", x[ i ], y );
}
}
