Re: MI-L Testing to ensure a string is numeric

[Robert Crossley]

A quick one would be:

Code...
If IsNumeric(x) Then
        do something knowing that it is a number
Else
        do something else because it isn't a number
End If
More Code...

Function IsNumeric(ByVal sTestStr as String) As Logical

If Str$(Val(STestStr)) = sTestStr Then
        IsNumeric = TRUE
Else
        IsNumeric = FALSE
End If
End Function

You can muck around with stripping spaces etc, and adding error handling

Listers,

Does anyone have a method using MapBasic to test whether a string is
numeric?  I have a dialog with an edittext box that needs a numeric
input.  Even if the solution is just a big hack that would be OK, since
I am going to make a logical MB function along the lines of
IsNumeric("123") = TRUE or something.
Thanks, will sum.
