'($1,925.46)' asNumber

Joseph Alotta
Greetings,

I want to convert a String with parenthesis and dollar sign to a Number or Float.

 '($1,925.46)’ asNumber

Is there something out of the box that does this, or do I have to write it myself, character by character?

Should I use a ReadStream?


Sincerely,

Joe.

Hi Joe,

If you know the format is consistent and you don't really need much error handling then something like this would work

('($1,925.46)' reject: [:e | '($),' includes: e]) asNumber

All the best,

Ron Teitelbaum

Thanks, Ron.  I needed to preserve the negative, so I append a minus sign, then use your snippet.
,

str := '($1,925.46)' .
('(*)' match: str ) ifTrue: [str := '-', str].
str := str reject:  [:e | '($,)' includes: e].
num := str asNumber  => -1925.46

Sincerely,

Joe.
