Returns the inverse hyperbolic sine.

Category:

Hyperbolic

Syntax

ARSINH(x)

x

specifies a numeric constant, variable, or expression.

Range:

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

[equation]

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
