atan x
Operand types:
x: Number
Type of returned value:
Description:
Arctangens of x, result in degrees.
Example:
_angle = atan 1 ..........Result is 45
Notes:
Using atan x is fine if you can be certain that x is a finite number.
For example:
_angle = atan 1/0
will create a divide by zero error, even though the angle is 90.
