LISP Functions ⤴
← (angle)

(angtof)

(angtos) →

(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.

Examples

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

NOTES

    • 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.
