Description

Returns the inverse cosine of x, in that if dcos(val)=n, darccos(n)=val, and the resulting number will be between 180 and 0.

NOTE:This will only accept a number between -1 and 1 (anything else will throw an error).

Syntax:

darccos(val)

Returns:

Real

Example:

val = arccos(-1);

This will set "val" to 180.
