(angtof string [mode])

Change this angle to a real number.

This function converts a string that contains an angle to a real number in radian format. The optional mode specifies the format of the "number" in the string:

Mode value String format
0 Decimal degrees
1 Degrees-minutes-seconds
2 Grad
3 Radian
4 Surveyor's units

NOTE This command fails if the text of the string is not recognizable as an angle measurement.


Code Returns
(angtof "90") 1.57080
(angtof "90" 0) 1.57080
(angtof "90d30'10\"") 1.57957


    • The backslash denotes that there is a quote within the string. When LISP sees the second quote, it knows this is the end of the string.
    • The angtof function is the opposite of the angtos function.
