[REBOL] Re: decimal woes

Hi Maxim, On Friday, July 18, 2003, 7:28:06 PM, you wrote: MOA> Do you think this means that print and probe do not contain MOA> all digits of the internal hw decimal value? Of course they don't. The internal representation is binary, while they print in decimal. There's no point in showing an amount that is lower than the error caused by the internal representation. However, since you use repeated additions, this error sums up and becomes "visible", i.e. big enough that PRINT thinks it is worth showing. In your case, fixed point arithmetic is probably the best solution. If you want to use floating point, you have to take the error into account. Or, at least you have to avoid operations that can make the error grow, as in: i: 0 loop 50 [ probe time: 2 * i / 100 i: i + 1 ] Regards, Gabriele. -- Gabriele Santilli <[g--santilli--tiscalinet--it]> -- REBOL Programmer Amiga Group Italia sez.
