Action
Returns the Arctangent of a floating point variable in radians.
Syntax
var = ATN( float )
Remarks
Var |
A float variable that is assigned with the arctangent of variable float. |
float |
The float variable to get the arctangent of. |
All trig functions work with radians. Use deg2rad and rad2deg to convert between radians and angles.
Floating point variables can be of the single or double data type.

Example
$regfile = "m48def.dat" ' specify the used micro
$crystal = 8000000 ' used crystal frequency
$baud = 19200 ' use baud rate
$hwstack = 32 ' default use 32 for the hardware stack
$swstack = 10 ' default use 10 for the SW stack
$framesize = 40 ' default use 40 for the frame space
Config Com1 = Dummy , Synchrone = 0 , Parity = None , Stopbits = 1 , Databits = 8 , Clockpol = 0
Dim S As Single , X As Single
S = Atn(1) * 4
Print S ' prints 3.141593 PI
