isnumeric in vbscript

[sweetleaf]

I have a section of vbscript in an asp page which checks that a variable is a number. it works for the most part but fails whenever the variable contains a "d" or an "e" (upper or lower case).

A co-worker told me that a number concantenated with "e" can be interpreted by the asp engine as an exponential number.. thus the variable will be considered numeric..
what about a number concantenated with a "d"?

Thanks

First: Sorry for my english, because i am a brasilian.

I tested your problem and I have a answer for you.
When you declare or not a variable in VBScript it is considered a variant type then it have any kide of value and if you atributed a value like a123, it is considered a numeric value but if You write a Response.Write Variable that return a numeric value but this is empty.

I expected have help you.
