bb3df95d13 Define *ai-v4mapped* to zero on platforms where AI_V4MAPPED is undefined. 
This change defines *ai-v4mapped* to zero when AI_V4MAPPED is undefined
and similarly for *ai-all* (similar to other patches). This allows
(srfi 106) to be available on NetBSD and other platforms without
AI_V4MAPPED and is the recommended behaviour by the author of SRFI-106:

Implement r7rs round to even behaviour for half integers
 2024-02-02 21:31:52 -05:00
Yorick Hardy
4bbceeb4d6 round half-integers to even instead of away from zero 
This changes the behaviour to match r7rs (round x) instead of C round(x).

An answer to https://stackoverflow.com/questions/32746523/ieee-754-compliant-round-half-to-even
suggests using remainder(). The following will work if FE_TONEAREST is defined, but C11
requires FE_TONEAREST to be defined if and only if the implemenetation supports it in
fegetround() and fesetround() [Draft N1570]. On the other hand, remainder() must be defined.
C23 will have roundeven(), but this is not yet available on all platforms.
The behaviour of remainder is described in Draft N1570, page 254, footnote 239.

Alternative implementation:

  double round_to_nearest_even(double x)
  {
  #pragma STDC FENV_ACCESS ON
    int mode;
    double nearest;
    mode = fegetround();
    fesetround(FE_TONEAREST);
    nearest = nearbyint(x);
    fesetround(mode);
  #pragma STDC FENV_ACCESS OFF
    return nearest;
  }

7d8f70fb07 add more tests for rounding 
r7rs requires (round x) to round to even when x is halfway between
two integers, while C requires round(x) to round away from zero.

334787b6d6 Issue #517 - Raise error when reading invalid number 
Previously #f was returned in this case but it is more correct to raise an error instead. This prevents weird edge cases and is more consistent with other schemes.
