RE: Floating point math within Vedit

Mr. Lindgren has written about having Vedit do arbitrary precision

floating point math. Something like Unix bc or dc. I wrote a Vedit

macro which is arbitrary precision calculation of floating point

numbers. To use FPMATH10.ZIP the Vedit user places each part of

an equation into some text registers. Next the user passes the

text registers numbers to my subroutine. It builds these parts into

a single equation and solves it. It returns the results back to a

text register.

The benchmark for this FPMATH10.ZIP is about 63. msec per equation.

Arbitrary precision performance is a function of math operator

and string lenght. It is a wide range. Multiplication is slow.

Division is very slow.

Mr Ziemski's FLOATMATH.VDM, is 2.2 msec per equation.

My earlier work, FPMATH09.ZIP, is .42 msec per equation.

Use Vedit System("command") to solve the equation about is 200 msec

per equation.

One of these methods may guide the few Vedit users that want

floating point math within Vedit. I will Email FPMATH09.ZIP or

FPMATH10.ZIP when requested.

Thank you

Yes, I'm curious. ;-)
Please send your macros to me.
