Converting a string containing dots to integer

Hi all,

I'm parsing some text which contains numbers like "8.324" and I would
like to convert it to integer. The problem is that asNumber and
asInteger don't make the trick because of the dot ("."), which is there
to indicate thousands, not decimal values. Which is the proper message
to send?

Cheers,

Offray

Re: Converting a string containing dots to integer

Do you have more details?

Such as, do you have values with more than one dot ? (e.g. 1.436.782)

Do you have values with no dot?

This might do the trick:

(Number readFrom: ('8.524.757' copyReplaceAll: '.' with: '')) asInteger

or even nicer (and simpler)

('8.524.757' reject: [:char | char == $.]) asInteger

If it's for the thousand you can use that:

(myStringNumber copyWithoutAll: '.') asNumber

To find this kind of methods you can use the finder (world -> Tools). You select "example" and you search for things like :

'1.234'.'.'.'1234'

and that will give you:

'1.234' copyWithoutAll: '.' first -> '1234'
