    I am sure this is about the simplest question possible for b4ppc. I can't find in math or strings help, how to do this (string to number). I want to convert a string eg. "21.6" to an array integer (216).

    Qbasic had a command val().

    Hi

    NSBasic also had a "val()" command. But how about the following:

    Sub......
    Dim A

    A=Substring("123.6",1,5)
    A=format(a,"N3")
    End Sub

    Does your string actually have the inverted commas? If so get rid of them and format it.

    Regards

    Hi Ceaser

    I don't think the sub does it. I have a string, and I want an int16.
    The string "21.6" then becomes the int16 216. I don't thin I can put
    string types into an integer array.

    The decimal point can easily be eliminated from the string but I put it
    there in case a command may also handles that.

    Basic4ppc automatically converts strings and numbers (floating point numbers) as needed.
    If you want to convert a value to an integer you can use the Round keyword.
    If you just want to remove the decimal point:
    Code:
    x = StrReplace(x,".","")

    Ok. Now I get it

    It seems that the compiler handles it.

    If I assign int16 matrix(0,0)=20.6 and then place matrix(0,0) in a text box, I get "20".

    Whereas if I assign int16 matrix(0,0)=20.6*10, and place matrix(0,0) in a text box, I get "206", and if I place matrix(0,0)/10 in the text box, I get "20.6".

    I haven't seen that before. I would expect errors. So I just needed the nerve to try it.

    Very nice.
