acosh function

Input type Output type

This function calculates the hyperbolic arcsine of the argument and returns the result. If the argument is of type int, it is first converted to float by the compiler.

Examples:

  acosh(2)      ; 1.3170  acosh(2.0)    ; 1.3170  acosh((2,0))  ; (1.3170, 0)    

Notes

  • acosh(cosh(x)) is equal to x.
  • The argument should be greater than -1. Otherwise this function will return an invalid value. See Invalid operations.
