    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 ) );
    }
