I checked the AppleSoft manual. It had 5 byte "real" numbers (page 148 ), from -1E38 to +1E38, with about 9 digits of precision ( page 4 )[1]. That was my first computer with floating-point, and my dad's HP-45 was my first calculator. :) A 2-byte float sounds like a lot of bit-shifting and masking for not much range... take care, *brianW [1] http://www.classiccmp.org/cini/pdf/Apple/AppleSoft%20II%20Basic%20Programming%20Manual.PDF > > -- > Cheers, > Kein-Hong Man (esq.) > Kuala Lumpur, Malaysia > ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
