This sounds like a very nasty work around someone might need to make up for bad coding habits. You'd probably be better off just assuming it's numeric and use try and except to deal with the cases when it's not.

Topic hijack!

Code: [Select]

function is_numeric(const source: string):boolean;
begin
try
strtoint(source);
result := true;
except
result:=false;
end;
end;

Checks for an integer, so if you want floating point numbers as well just change strtoint into strtofloat.
