Conversion Functions
A part of a circle or an angle can be measured in different units: degrees, radians, gradians or cycles. With the conversion functions an angle can be converted easily from one angle unit to another, for example from degrees to radians.

Overview
The following conversion functions are available.| Function | Description |
|---|---|
| Rad2Deg(x) | Convert x from radians to degrees One radian is equal to 360/(2*Pi) degrees |
| Rad2Grad(x) | Convert x from radians to gradians One radian is equal to 400/(2*Pi) gradians |
| Rad2Cycle(x) | Convert x from radians to cycles One radian is equal to 1/(2*Pi) cycles |
| Deg2Rad(x) | Convert x from degrees to radians One degree is equal to 2*Pi/360 radians |
| Grad2Rad(x) | Convert x from gradians to radians One gradian is equal to 2*Pi/400 radians |
| Cycle2Rad(x) | Convert x from cycles to radians One cycle contains 2*Pi radians |
Examples
'Examples of using Conversion functions
'set the system variable angles to radians
Angles = Rad
Angles mode set to Radians
'suppose an angle is given in degrees
myAngle = 45
myAngle = 45
'calculate the angle in radians
myAngleRadians = Deg2Rad(myAngle)
myAngleRadians = 0.785398163
'calculate the sine of the angle
Sin(myAngleRadians)
Ans = 0.707106781
'Some special values
Rad2Cycle(2 * Pi)
Ans = 1
Rad2Deg(2 * Pi)
Ans = 360
Rad2Grad(2 * Pi)
Ans = 400
Rad2Deg(0.25 * Pi)
Ans = 45
Rad2Grad(1 * Pi)
Ans = 200
'You can use combinations of conversion functions
'to convert for example from degrees to cycles
Deg2Rad(Rad2Cycle(360))
Ans = 1
Grad2Rad(Rad2Deg(200))
Ans = 180
