IsNumeric(value) should return false if value "can not be
successfully converted to a Double." Instead I get the
following error message: "Input string was not in a
correct format."
I use the following function in a validating class to use
when needed. (Value = H880118A gave the error (like
other 'unconvertible' strings))

I have received the following feedback for the two functions bellow:
"The ISNUMERIC test is WORTHLESS for checking for an INT value, because
ISNUMERIC will happily accept DOUBLE values, such as 89.11998811777 and
other values that are simply *NOT* INT values."

Hello,
Does anyone have a good/reliable approach to implementing an IsNumeric()
method that accepts a string that may represent a numerical value (eg. such
as some text retrieved from an XML file)? Thus if you pass it "1" or
"5.12345" it returns true, but "1b3q" it returns false? I know VB has this
sort of function, but was wondering how to...

All,
I think I may have uncovered a bug in the IsNumeric function, or at least a
misunderstanding on functionality.

section that lists the Times, Buildings and rooms for courses.
In this section I have a function called PadCell that takes3 parameters, one
the value,...

What's the .net framework equivalent of the vb function isnumeric? If there
isn't one, how can I test a string variable to see if its a number or not?
I don't want to use isnumeric if possible

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
