FUNCTION REFERENCE ATAN2(A, B)
ATAN2(A, B)
ARGUMENT TYPE DESCRIPTION
a float The value of the side that is opposite the angle theta.
b float The value of the side that is adjacent to the angle theta
DESCRIPTION
This function is equivalent to atan(a/b), except that it also considers the sign of a and b,
and thereby ensures that the return value is in the appropriate quadrant. It is also capable of
handling a zero value for b, thereby avoiding the infinity that would result if the singleargument
form of tan were used instead.
FUNCTION TYPE
This function is passive.
RETURN TYPE
float.
EXAMPLE
theta := atan2(1,1)
