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,

[Ron Teitelbaum] Excellent! Well done!
