自然对数

For example, 10 3 = 1,000; therefore, log 10 1,000 = 3. The kinds most often used are the common logarithm and the natural logarithm.

如，10 3=1，000；于是log 101，000=3。通常使用的有常用对数和自然对数

The expm1 function returns the value of Ex-1, where E is Euler's constant (approximately 2.7183) and x is the number passed to it.

expm1函数的作用是：计算 e（自然对数的底，其数值大约等于2.7183）的指数；它返回了exp 1的值，甚至当number的值接近零也能计算出准确结果。

The most important exponential function is ex, the inverse of the natural logarithmic function.

最重要的指数函数是ex，即自然对数函数的反数

The most important ex ponential function is ex , the inverse of the natural logarithmic function.
