• The ValDec function starts reading the string with the leftmost character and stops at the first character that it does not recognize as being part of a valid number. For example, the statement:

  iNumber = ValDec("1A1")

  returns 1.

• &O and &H (the octal and hexadecimal prefixes) are recognized by the ValDec function.

• Currency symbols, such as $ and , and delimiters, such as commas, are not recognized as numbers by the ValDec function.

• The ValDec function only recognizes the period (.) as a decimal delimiter .

• Prior to processing expression , ValDec removes spaces, tabs, and line-feed characters .

Programming Tips and Gotchas

If you are developing an international application, you should use the CDec function to convert strings to numbers, since CDec can recognize all decimal separators.
