(distof string [mode])

"Convert a string to a real number.

This function converts a string that contains a real number to a real number (distof is short for DIStance TO Floating point). The distof is opposite the rtos function. The optional mode specifies a number format, like the rtos function:

Mode	Format
1	Scientific.
2	Decimal.
3	Engineering: feet and decimal inches.
4	Architectural: feet and fractional inches.
5	Fractional.

Examples

Code	Returns
(distof "2.3698E001")	23.698
(distof "2'-5.25\"" 3)	29.25

NOTE The backslash denotes that there will be a quote within the string. Once LISP sees the second quote, it knows it's the end of the string.
