24.113. Math.log( ): compute a natural logarithmECMAScript v124.113.1. SynopsisMath.log(x) 24.113.1.1. Arguments
24.113.1.2. ReturnsThe natural logarithm of x. 24.113.2. DescriptionMath.log( ) computes logex, the natural logarithm of its argument. The argument must be greater than zero. You can compute the base-10 and base-2 logarithms of a number with these formulas: log10x = log10e · logex log2x = log2e · logex These formulas translate into the following JavaScript functions: function log10(x) { return Math.LOG10E * Math.log(x); } function log2(x) { return Math.LOG2E * Math.log(x); } |
