atan

atan x

Operand types:

x: Number

Type of returned value:

Number

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 valid.
Better is to use atan2
