Computes the arccosine (in radians) of the specified argument.

Format:
acos(exprn)
Arguments:
exprn
Expression to compute the arccosine of (float).
Return type:
float
Error conditions:
Returns bottom if exprn evaluates to bottom, or if exprn is not in the domain of arccosine (which is [-1.0,1.0]).
Example:

Code:
value = acos(1)
  Sets value to the arccosine of 1, which is approximately 0.0
  (possibly with some rounding error.)
