Tries to convert numbers in query string to invariant culture format before passing to YAMP, and the other way around when presenting result from
YAMP. Nothing fancy, just a regular expression scanning for substrings consisting of number, decimal separator and group separator, trying a
parse and convert on them. Translation is skipped if no conversion between user locale and invariant culture number format is necessary.
Closes#436.
Added functions I commonly use on e.g. google calculator but were missed by parser.
Specifically I added:
e (constant like pi)
tan, arcsin, and arctan
log and ln
