exp2

Base 2 exponential function.

Usage

var exp2 = require( '@stdlib/math/base/special/exp2' );

exp2( x )

Evaluates the base 2 exponential function.

var v = exp2( 3.0 );
// returns 8.0

v = exp2( -9.0 );
// returns ~0.002

v = exp2( 0.0 );
// returns 1.0

v = exp2( NaN );
// returns NaN

Examples

var randu = require( '@stdlib/random/base/randu' );
var exp2 = require( '@stdlib/math/base/special/exp2' );

var x;
var i;

for ( i = 0; i < 100; i++ ) {
    x = (randu()*100.0) - 50.0;
    console.log( '2^%d = %d', x, exp2( x ) );
