Yukihiro "Matz" Matsumoto fddc7650ca numeric.c (int_ceil): should rename mrb_bint_add_d to mrb_bint_add_n 2024-09-15 04:00:52 +09:00
Yukihiro "Matz" Matsumoto bdbf8536a7 mruby-bigint: rename add_d and sub_d to add_n and sub_n respectively

 2024-09-15 03:02:41 +09:00
Yukihiro "Matz" Matsumoto e8bb03da40 numeric.rb (step): iterate over integers even if end is a float 
It used to check all `start`, `end` and `step`. If either of them are
float number, `#step` iterated over float number. Now we don't check the
type of `end` argument.

 2024-06-27 08:55:28 +09:00
Yukihiro "Matz" Matsumoto b8f968b4a3 numeric.c (mrb_cmp): no need to check respond_to?(:<=>) 
Because every object responds to `<=>`.

Yukihiro "Matz" Matsumoto db8368fa86 numeric.c: remove bit operations methods from Float class; #6197 
mruby used to use float numbers for overflown integers before we
implemented big integers. Now we don't need bit operations for float
numbers anymore. Also removed tests for shift operations for float
numbers.

dearblue 8ecfacefca Prohibit Class#allocate in a different way 
The method introduced by #5979 causes a fault by swapping classes.

```console
% bin/mruby -e 'Method = Proc; p Object.method(:inspect)'
zsh: segmentation fault (core dumped)  bin/mruby -e 'Method = Proc; p Object.method(:inspect)'
```

After applying this patch, a `TypeError` exception will be raised.

```console
% bin/mruby -e 'Method = Proc; p Object.method(:inspect)'
trace (most recent call last):
        [1] -e:1
-e:1:in method: allocation failure of Proc (TypeError)
```

However, if the `mrb_vtype` is the same object, the same care must still be taken as before.

```console
% bin/mruby -e 'Method = Binding; p method(:puts).eval("12345")'
trace (most recent call last):
        [1] -e:1
-e:1:in eval: wrong argument type nil (expected Proc) (TypeError)
```

fixed #5987
 2023-04-15 22:39:05 +09:00
dearblue d3128ce58a Allow Class#allocate to be prohibited 
Calling `Class#allocate` with `UnboundMethod#bind_call` usually succeeds without problems.
If this behavior does not make us happy, we can now prohibit it with `MRB_SET_INSTANCE_TT(klass, MRB_TT_UNDEF)`.

At the same time, it applies to the `Binding`, `Complex`, `Data`, `Float`, `Integer`, `Method`, `Rational` and `UnboundMethod` classes.
