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 ) );
}
