* libguile/numbers.c (scm_finite_p): Add new predicate `finite?' from R6RS to guile core, which returns #t if and only if its argument is neither infinite nor a NaN. Note that this is not the same as (not (inf? x)) or (not (infinite? x)), since NaNs are neither finite nor infinite. * test-suite/tests/numbers.test: Add test cases for `finite?'. * module/rnrs/base.scm: Import `inf?' as `infinite?' instead of reimplementing it. Previously, the R6RS implementation of `infinite?' did not detect non-real complex infinities, nor did it throw exceptions for non-numbers. (Note that NaNs _are_ considered numbers by scheme, despite their name). Import `finite?' instead of reimplementing it. Previously, the R6RS implementation of `finite?' returned #t for both NaNs and non-real complex infinities, in violation of R6RS. * NEWS: Add NEWS entries, and reorganize existing numerics-related entries together under one subheading. * doc/ref/api-data.texi (Real and Rational Numbers): Add docs for `finite?' and scm_finite_p. |
