Decimal Plugin for Mac

From Robert Delaney:

Decimal Plugin is a REAL Studio plugin that handles big numbers as exact decimals. Decimal can handle big numbers whose size is only limited by available memory. Decimal can be freely mixed with REALbasic's numeric types. The Decimal type can exactly represent any finite decimal. One can think of a Decimal as two numbers (i, e), where i is an integer of any length, and e is of Integer type and is the exponent for base ten. That is: (i, e) = i x 10^e.
