numeric.c: use NUM2DBL

2017-09-22T03:05:02+00:00

* numeric.c (fix_fdiv_double), bignum.c (rb_big_fdiv_double): use
  NUM2DBL on unknown object.  RFLOAT_VALUE is only appliicable to
  T_FLOAT object.  [ruby-core:82924] [Bug #13928]

make Integer#{round,floor,ceil,truncate} always return integer

2017-05-06T19:58:12+00:00

* numeric.c (int_round): return integer (self) instead of float
  for Integer#round with positive ndigits argument, because
  conversion to float introduces errors for large integers.
* numeric.c (int_floor): ditto for Integer#floor.
* numeric.c (int_ceil): ditto for Integer#ceil.
* numeric.c (int_truncate): ditto for Integer#truncate.

* test/ruby/test_integer.rb: adjust test cases and add some more.

bignum.c: fix inexact estimation

2017-04-15T15:29:09+00:00

* bignum.c (estimate_initial_sqrt): estimated square root is
  inexact if it is not equal to its ceil, needs Newton's method.

Integer.sqrt argument check

2017-02-24T09:39:17+00:00

internal.h: change the default rounding mode to half-up

2016-12-10T02:36:16+00:00

* test/ruby/test_rational.rb: ditto.

* test/test_mathn.rb: ditto.

2016-11-25T06:28:00+00:00

* numeric.c (round_half_down, int_round_half_down): support
  round-down mode.

numeric.c: round to nearest even

2016-11-05T09:49:39+00:00

* numeric.c (flo_round, int_round): support round-to-nearest-even
  semantics of IEEE 754 to match sprintf behavior, and add `half:`
  optional keyword argument for the old behavior.

2016-11-01T22:34:30+00:00
