* libguile/numbers.c (scm_rational_p): Return #f for infinities and NaNs, per R6RS. Previously it returned #t for real infinities and NaNs. They are still considered real by scm_real `real?' however, per R6RS. Also simplify the code. (scm_real_p): New implementation to reflect the fact that the rationals and reals are no longer the same set. Previously it just called scm_rational_p. (scm_integer_p): Simplify the code. * test-suite/tests/numbers.test: Add test cases for `rational?' and `real?' applied to infinities and NaNs. * doc/ref/api-data.texi (Real and Rational Numbers): Update docs to reflect the fact that infinities and NaNs are no longer rational, and that `real?' no longer implies `rational?'. Improve discussion of infinities and NaNs. * NEWS: Add NEWS entries, and combine with an earlier entry about infinities no longer being integers. |

This directory contains documentation on the Guile core. -*-text-*- The documentation consists of the following manuals. - The Guile Tutorial (guile-tut.texi) contains a tutorial introduction to using Guile. - The Guile Reference Manual (guile.texi) contains (or is intended to contain) reference documentation on all aspects of Guile. - The Revised^5 Report on the Algorithmic Language Scheme (r5rs.texi). Please be aware that this is all very much work in progress (apart from the Revised^5 Report). Bug reports and contributions are welcome! The file `oldfmt.c' contains a function which can be used by application writers to support both old-style and new-style error format strings. The `sources' directory includes some stuff relevant to the Guile reference manual, and which may eventually be folded in to it. It's not immediately relevant, however, which is why it's not in this directory. The Revised^4 Report (r4rs.texi) is no longer in this distribution, as it is completely superseded by the Revised^5 Report. If you need to consult R4RS, it is still widely available, for example at http://www-swiss.ai.mit.edu/projects/info/SchemeDocs/r4rs/.
