The Arithmetic Operator

The arithmetic operator component includes the four basic arithmetic operator signs and two hash symbols:

• + (plus)
• - (minus)
• * (multiply by)
• / (divide by)
• P (hash-plus or -add)
• M (hash-minus or -subtract)

A hash total allows you to validate the accuracy of certain fields. For example, you can sum the numeric equivalent of a customer number field as a check on operator input.
