Version 1.5 of the Precision Plugin now has x86 support. So it can be used

in the construction of REALbasic applications for Mac OS 9.x, Mac OS X, and

Windows.

Bob Delaney is releasing his freeware Precision Plugin. It allows

mathematical operations on very large numbers. It is a light version of his

MPCalc plugin, but is not based on an RPN calculator interface. Rather it

is more like C in its behavior. As an example, here’s how you would divide

two very large numbers at a precision of 20. The first argument number is

divided by the second.

dim result As String

MPLsetPrecision 20

result=MPLdiv(“1.234567e2538”, “5.6789e1234”)

You would find in result the string:

2.1739544630122030675e1303

You can do an MPLSetPrecision up to 30000. Of course, computations go

slowly at large precisions.

Precision Plugin has almost all the REALbasic functions, but at much higher

precisions. It also has flow control functions for looping. And functions

can be nested. There is extensive checking of inputs to catch incipient

mathematical errors or overflow or underflow.
