The ARSINH function computes the inverse hyperbolic sine. The
ARSINH function is mathematically defined by the following equation, where

Replace the infinity symbol with the largest double precision number
that is available on your machine.
The following example computes the inverse hyperbolic sine.
data _null_;
x=arsinh(5);
x1=arsinh(-5);
put x=;
put x1=;
run;
SAS writes the following output to the log:
x=2.3124383413
x1=-2.312438341
