locale-parse-number

Arguments: string &key (locale *locale*) (start 0) (end nil)

Arguments:

• string is a string.
• locale is a locale.
• start is a bounding index designator of string. The default is 0.
• end is a bounding index designator of string. The default is nil.

locale-parse-number parses the number in string, with bounds designated by start/end, assuming that the number is in locale's format (i.e., follows locale's thousands separator and decimal point rules).

It is an error for the boundary designated by start/end in the string not to consist entirely of the representation of the number, possibly surrounded on either side by whitespace characters.

The first value returned is the number that was parsed. The type is that of *read-default-float-format*.

The second value returned is the index into the string of the delimiter that terminated the parse, or the upper bounding index of the substring if the parse terminated at the end of the substring.

Example:

(locale-parse-number "1.234,56" :locale :de_DE) 
  ==> values 1234.56 7
