Package Exports

@stdlib/math-base-special-pow

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/math-base-special-pow) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Exponential Function

$NPM version$ $Build Status$ $Coverage Status$ $dependencies$

Exponential function.

The exponential function is defined as

$Exponential function$

where b is the base and x is the exponent.

Installation

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

Usage

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

pow( base, exponent )

Evaluates the exponential function.

var v = pow( 2.0, 3.0 );
// returns 8.0

v = pow( 4.0, 0.5 );
// returns 2.0

v = pow( 100.0, 0.0 );
// returns 1.0

v = pow( 3.141592653589793, 5.0 );
// returns ~306.0197

v = pow( 3.141592653589793, -0.2 );
// returns ~0.7954

v = pow( NaN, 3.0 );
// returns NaN

v = pow( 5.0, NaN );
// returns NaN

v = pow( NaN, NaN );
// returns NaN

Examples

var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var pow = require( '@stdlib/math-base-special-pow' );

var b;
var x;
var i;

for ( i = 0; i < 100; i++ ) {
    b = round( randu()*10.0 );
    x = round( randu()*10.0 ) - 5.0;
    console.log( '%d^%d = %d', b, x, pow( b, x ) );
}
