Numbers in Variants
When storing numbers in variant variables, the data type used is the most compact type possible. For example, if you first assign a whole number to the variant it will be stored as an integer or long. If you assign a number with a fractional component, it is stored as a single or double.
For doing numeric operations on a variant
variable, it is sometimes necessary to determine if the value
stored is a valid numeric, thus avoiding an error. This can be done
with the IsNumeric( )
function.
