The angtof function converts a string interpreted as an angle based upon a given string-format for a unit mode to a floating-point number value.
The value of mode is interpreted as follows:

| -1 | The current value of the system variable AUNITS (Angular Units) is used |
| -1 | The current value of the command variable SetAngUnt (Set Angular Units) is used |
| 0 | Degrees |

The function returns the result in radians.
If angtof does not succeed, it returns nil.
