@stdlib/math-base-special-pow

Exponential Function

Exponential function.

The exponential function is defined as

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 ) );
}
