Text To Integer

[aussiedave]

Hi all can you help me ?.

I have text boxes that load info from an ini file.

Example: $50,000

so that I can add up the progressive totals of the text in the boxes as
they become available I need to change them to integers.

I'v racked my brains but cannot come up with an answer in MMF2.

Another way of doing it would be fine

Thanks

As I'm sure you are aware, using the str$() function or retrieve numeric value of edit box returns a 0 when you start including other characters.

To get around this you can do some stuff with regular expressions (which is fairly advanced). You would need to use "[0-9]" as the regular expression to process the incoming string and filter out all but the characters 0-9.

Alternatively, you can manually loop through each string with a fast loop, examining a single character at a time using mid$() in the expression editor. Add the character to the end of a new temporary string ONLY if it is a number - by the time you've gone through each character in the original string you'll obviously have stripped all but the numbers then.

I can't think of anything else obvious right now, hope this helps... if you want me to explain step-by-step about the mid$() method just message me or reply here <img src="/center/images/graemlins/smile.gif" alt="" />

Text to Integer:

Adding up 2 string integers to make a new string:
[:"blue"]
str$(val(text1)+val(text2))[/]

i'm not quite sure if thats what you mean. If there is a currency sign before the number then either save the values without the sign or use:[:"blue"]

str$(val(Right$(Text1,len(Text1)-1))+val(Right$(Text2,len(Text2)-1)))[/]

You can always write a simple function in Lua to do the dirty work of squeezing out all non-numerical characters. That's probably what I would do, if I couldn't think of any simple pure-MMF solutions :P

Thank you for taking the time to reply.

I am working on your answers right now.

you can always use string parser to remove commas and dollar signs.
adding text is how raytrace explained. use val("text") to get an integer.
