Generic Inquiry: Return substring from a currency value (remove auto-inserted trailing 00s)

The mission with this generic inquiry is to show the payment amount value with the decimal stripped out. I’ve tried a few formulas but Acumatica seems to want to add 2 trailing 0s when I do that. 

Example:

The goal is, instead of showing $8321.05, to show:  832105

In SQL I’d want to return a substring, or trim 2 characters from the right side of the string. Here are a few examples of what I’ve tried:

• Try to get the field to display as a schema field ‘payment amount’
• Try to get the field to display as schema field ‘doc description’
• Try to return from the right side of the string, -2 positions: =Right(CStr( Replace(  [APPayment.CuryOrigDocAmt], '.' , '' ) ), -2)
• Try to cast the field as a decimal =Replace(  CDec([APPayment.CuryOrigDocAmt]), '.' , '' )
• Try to cast the field as a string  =Replace(  CStr([APPayment.CuryOrigDocAmt]), '.' , '' )

Any suggestions on this? Acumatica really seems to want to add those zeroes!
