AngleDegrees (Return Degrees)

The AngleDegrees declaration is used to set math functions in the program to return, or to expect as the source, degrees instead of radians.

Syntax

AngleDegrees

In the following test program (which finds the arccosine of a random value), AngleDegrees is placed at the beginning of the program. It causes the value returned by ACOS to be in degrees instead of radians.

'Set functions to Angles instead of radians
AngleDegrees

'Declare variables & constants
Public RNumber, ANumber
Dim Time(9)
Const Upper=1
Const Lower=-1

'Main program
BeginProg
  Scan (1,Sec,3,0)
    'Realtime(sec) is used as a seed for RND
    RealTime (Time())
    Randomize Time(6)
    RNumber=((Upper - Lower-1) * RND)
    ANumber=ACOS(RNumber)
  NextScan
EndProg

Remarks

The AngleDegrees instruction is placed in the declarations section of the program, before the code enclosed in the BeginProg/EndProg instructions.

AngleDegrees affects the following instructions that return an angle in radians: ATN, ATN2, ACOS, ASIN, RectPolar.

Angle Degrees affects the following instructions that expect an angle in radians as the source: COS, TAN, and SIN.

Negative radians will convert to negative degrees.
