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



[Ron Teitelbaum] Excellent!  Well done!

,

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

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

[Newbies] '($1,925.46)' asNumber

2016-07-01 Thread 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.
