Lines: 17 In-reply-to: kend@data.UUCP's message of 21 Nov 90 17:10:40 GMT MacScheme 2.0 produces -1.805916207174113e21 which (apparently) is similar to other IEEE 754 machines. MacScheme has {flonums, bignums} but no rationals. The manual says, "Flonums are real numbers approximated by a 32-bit floating point format similar to the IEEE standard." Hmmmm. Elk 1.2 on a SPARCstation 1 produces the same answer as reported for Elk 1.1 on a Sun3. BTW, Elk has bignums at least. -- Vladimir -- ============================================================================== Vladimir G.
