AngleDegrees

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

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, COSH, TAN, TANH, SIN, SINH.

Negative radians will convert to negative degrees.

Bit Shift Operators (<< and >>)

The bit shift operators (>> or <<) perform an arithmetic bit shift operation on a

numeric expression.

Syntax

<< : Bit shift left

Variable = Numeric Expression >> Amount

>> Bit shift right

Variable = Numeric Expression >> Amount
