Mark H Weaver ff62c16828 Add two new sets of fast quotient and remainder operators ... * libguile/numbers.c (scm_euclidean_quo_and_rem, scm_euclidean_quotient, scm_euclidean_remainder, scm_centered_quo_and_rem, scm_centered_quotient, scm_centered_remainder): New extensible procedures `euclidean/', `euclidean-quotient', `euclidean-remainder', `centered/', `centered-quotient', `centered-remainder'. * libguile/numbers.h: Add function prototypes. * module/rnrs/base.scm: Remove incorrect stub implementations of `div', `mod', `div-and-mod', `div0', `mod0', and `div0-and-mod0'. Instead do renaming imports of `euclidean-quotient', `euclidean-remainder', `euclidean/', `centered-quotient', `centered-remainder', and `centered/', which are equivalent to the R6RS operators. * module/rnrs/arithmetic/fixnums.scm (fxdiv, fxmod, fxdiv-and-mod, fxdiv0, fxmod0, fxdiv0-and-mod0): Remove redundant checks for division by zero and unnecessary complexity. (fx+/carry): Remove unneeded calls to `inexact->exact'. * module/rnrs/arithmetic/flonums.scm (fldiv, flmod, fldiv-and-mod, fldiv0, flmod0, fldiv0-and-mod0): Remove redundant checks for division by zero and unnecessary complexity. Remove unneeded calls to `inexact->exact' and `exact->inexact' * test-suite/tests/numbers.test: (test-eqv?): New internal predicate for comparing numerical outputs with expected values. Add extensive test code for `euclidean/', `euclidean-quotient', `euclidean-remainder', `centered/', `centered-quotient', `centered-remainder'. * test-suite/tests/r6rs-arithmetic-fixnums.test: Fix some broken test cases, and remove `unresolved' test markers for `fxdiv', `fxmod', `fxdiv-and-mod', `fxdiv0', `fxmod0', and `fxdiv0-and-mod0'. * test-suite/tests/r6rs-arithmetic-flonums.test: Remove `unresolved' test markers for `fldiv', `flmod', `fldiv-and-mod', `fldiv0', `flmod0', and `fldiv0-and-mod0'. * doc/ref/api-data.texi (Arithmetic): Document `euclidean/', `euclidean-quotient', `euclidean-remainder', `centered/', `centered-quotient', and `centered-remainder'. (Operations on Integer Values): Add cross-references to `euclidean/' et al, from `quotient', `remainder', and `modulo'. * doc/ref/r6rs.texi (rnrs base): Improve documentation for `div', `mod', `div-and-mod', `div0', `mod0', and `div0-and-mod0'. Add cross-references to `euclidean/' et al. * NEWS: Add NEWS entry.		2011-01-30 23:00:38 +01:00
