描述

因为 LN10 is a static property of Math , you always use it as Math.LN10 , rather than as a property of a Math object you created ( Math is not a constructor).

范例

使用 Math.LN10

The following function returns the natural log of 10:

function getNatLog10() {
  return Math.LN10;
}
getNatLog10(); // 2.302585092994046
