Is Variable Numeric Method
The Is Variable Numeric method determines if the value of a variable is numeric. It returns one of the following values:
-1 (negative one). The expression is a Numeric data type or is a string that Siebel VB can interpret as a number.
0 (zero). The expression is not a Numeric data type or is not a string that Siebel VB can interpret as a number.
If numeric input is required, then you can use the Is Variable Numeric method to determine if the value that the user provides is a valid number before converting the input to a numeric data type.
