Natural Logarithm

Evaluate the natural logarithm.

Usage

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

ln( x )

Evaluates the natural logarithm.

var v = ln( 4.0 );
// returns ~1.386

v = ln( 0.0 );
// returns -Infinity

v = ln( Infinity );
// returns Infinity

v = ln( NaN );
// returns NaN

For negative numbers, the natural logarithm is not defined.

var v = ln( -4.0 );
// returns NaN

Examples

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

var x;
var i;

for ( i = 0; i < 100; i++ ) {
    x = round( randu() * 100.0 );
    console.log( 'ln(%d) = %d', x, ln( x ) );
}
