atanh function
| Input type | Output type |
| float complex | float complex |
This function calculates the hyperbolic arctangent of the argument and returns the result. If the argument is of type int, it is first converted to float by the compiler.
Examples:
atanh(0.5) ; 0.5493 atanh((0.5, 0)) ; (0.5493, 0)
Notes
- atanh(tanh(x)) is equal to x.
- The argument should be greater than -1 and smaller than 1. Otherwise this function will return an invalid value. See Invalid Operations.
