All mathematical functions return a numeric result and only accept numeric arguments.
The $FACOS Function
result=$FACOS(n)
This function returns the arc cosine of the argument n. The resulting value is in degrees. The
argument to $FACOS must be between -1 and 1 inclusive.
The $FASIN Function
result=$FASIN(n)
This function returns the arc sine of the argument n. The resulting value is in degrees. The
argument to $FASIN must be between -1 and 1 inclusive.
The $FATAN Function
result=$FATAN(n)
This function returns the arc tangent of the argument n. The resulting value is in degrees.
The $FATAN2 Function
result=$FATAN2(n1,n2)
This function returns the arc tangent of the expression n1/n2. The resulting value will be greater
than -180 degrees and less than or equal to 180 degrees. If the value of n1 is positive, the result is
positive. When the value of n1 is zero, the result will be zero if n2 is positive and 180 degrees if
n2 is negative. If the value of n2 is zero, the absolute value of the result will be 90 degrees. Both
n1 and n2 must not be zero.
