- inverse hyperbolic sine functions
cc [ flag... ] file... -lm [ library... ] #include <math.h> double asinh(double x);
float asinhf(float x);
long double asinhl(long double x);
These functions compute the inverse hyperbolic sine of their argument x.
Upon successful completion, these functions return the inverse hyperbolic sine of their argument.
If x is NaN, NaN is returned.
If x is ±0 or ±Inf, x is returned.
No errors are defined.
