This is a standard C arithmetic library. All functions are stored in the Math Table.
1. Math. Abs (X)
Function: returns the absolute value of X.
2. Math. ACOs (X)
Function: returns the arc cosine of X. The value x must be between-1 and 1.
3. Math.

At that time, a GSL log1p (x) code implementation was provided. However, I didn't want to understand why it was like that. I suddenly understood it when I read a post on shuimu recently.
The Code on GSL is as follows:
