2020-11-17Simplify `mrb_num_div_int()`.Yukihiro "Matz" Matsumoto
2020-11-14Integer operation should result in Integer.Yukihiro "Matz" Matsumoto

2020-10-12Remove obsolete `MRB_WITHOUT_FLOAT` macro from `numeric.c`.Yukihiro "Matz" Matsumoto
2020-10-12Stop warning on 64 bit platforms.Yukihiro "Matz" Matsumoto
2020-10-12Handle potential overflow in `int_div` and `flo_idiv`.Yukihiro "Matz" Matsumoto
2020-10-12Use `mrb_int_value()` instead of `mrb_fixnum_value()`.Yukihiro "Matz" Matsumoto
Where fixnum overflow can happen.
2020-10-12Reorganize `Integer` system.Yukihiro "Matz" Matsumoto
- Integrate `Fixnum` and `Integer` - Remove `Integral` - `int / int -> int` - Replace `mrb_fixnum()` to `mrb_int()` - Replace `mrb_fixnum_value()` to `mrb_int_value()`. - Use `mrb_integer_p()` instead of `mrb_fixnum_p()`
2020-10-12Make division by zero cause `ZeroDivisionError`.Yukihiro "Matz" Matsumoto
As described in ISO 15.2.30.
2020-10-12Rename `MRB_TT_FIXNUM` to `MRB_TT_INTEGER`.Yukihiro "Matz" Matsumoto
We still have `#define MRB_TT_FIXNUM MRB_TT_INTEGER` for compatibility.
2020-10-12Always add trailing `.0` in `Float#inspect`; ref #4225KOBAYASHI Shuji
Trailing `.0` is removed from `Float#to_s` and `Float#inspect` at 9d08025b. However, I think the more human-readable format is better for `Float#inspect`. For example, in the `Float#to_s` format, the failure message is not well understood when testing values including types by `eql?` (e.g. `Numeric#step` test). ```ruby assert "example" do exp = 1.0 act = 1 assert_operator(exp, :eql?, act) #=> Expected 1 to be eql? 1. end ```
2020-10-12Integrate `Fixnum` class into `Integer` classdearblue
* The `Fixnum` constant is now an alias for the `Integer` class. * Remove `struct mrb_state::fixnum_class` member. If necessary, use `struct mrb_state::integer_class` instead.
2020-10-12Rename float configuration option names.Yukihiro "Matz" Matsumoto
- `MRB_WITHOUT_FLOAT` => `MRB_NO_FLOAT` - `MRB_USE_FLOAT` => `MRB_USE_FLOAT32` The former is to use `USE_XXX` naming convention. The latter is to make sure `float` is 32bit float and not floating point number in general.
2020-10-12Use functions that take symbols to reduce string litrals in C.Yukihiro "Matz" Matsumoto
2020-10-12Use `mrb_funcall_id()` extensively.Yukihiro "Matz" Matsumoto
Except for support files e.g. `mruby-test/driver.c`, which are not target of symbol collection via `rake gensym`.
2020-10-12Fix argument error when built with MRB_WITHOUT_FLOAT flagssmallkirby
Fixed inproper argument of mrb_fixnum_value() called in integral_div(), when built with MRB_WITHOUT_FLOAT flag. Co-authored-by: taiyoslime <[email protected]> Co-authored-by: n4o847 <[email protected]>
2020-08-08Return `NaN` for `0/0`; d8e060dYukihiro "Matz" Matsumoto
2020-08-08Should not use `mrb_float_value()` with `MRB_WITHOUT_FLOAT`.Yukihiro "Matz" Matsumoto
2020-08-07Avoid `division by zero` undefined behavior.Yukihiro "Matz" Matsumoto
2020-06-25Remove unnecessary `break` from `numeric.c`.Yukihiro "Matz" Matsumoto
2020-06-20Add `mrb_get_arg1()` that retrieves single (and only) argument.Yukihiro "Matz" Matsumoto
`mrb_get_arg1()` raises `ArgumentError` if the method does not receive one argument. And replaces all `mrb_get_args(mrb, "o", &arg)` by the new function.

2019-09-26Use type predicate macros instead of `mrb_type` if possibleKOBAYASHI Shuji
For efficiency with `MRB_WORD_BOXING` (implement type predicate macros for all `enum mrb_vtype`).
2019-09-18Remove `mrb_get_args(mrb, "")`; ref 30f37872KOBAYASHI Shuji
2019-09-17Fix `Fixnum#(to_s|inspect)` argument specsKOBAYASHI Shuji

2019-09-14Remove `mrb_funcall` from `<=>` operations.Yukihiro "Matz" Matsumoto
2019-09-07Revert part of #4225Yukihiro "Matz" Matsumoto
Since in mruby, Integer and Float interchange frequently (mostly on overflow), so adding explicit `.0` can cause problems sometimes. For example: https://github.com/mattn/mruby-json/pull/40 https://github.com/pepabo/mruby-msd/pull/13 https://github.com/mattn/mruby-json/pull/42

2019-08-05Use new specifiers/modifiers of `mrb_vfromat()`KOBAYASHI Shuji
The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in my environment than before the introduction of new specifiers/modifiers (5116789a) with this change. ------------+-------------------+-------------------+-------- BINARY | BEFORE (5116789a) | AFTER (This PR) | RATIO ------------+-------------------+-------------------+-------- mruby | 593416 bytes | 593208 bytes | -0.04% libmruby.a | 769048 bytes | 767264 bytes | -0.23% ------------+-------------------+-------------------+-------- BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613, so I put it back.
2019-07-31Avoid `MRB_INT_MIN` to apply `fixdivmod`.Yukihiro "Matz" Matsumoto
`MRB_INT_MIN` is the only integer value that has no corresponding positive integer value (i.e. `-MRB_INT_MIN` = `MRB_INT_MIN`).
2019-07-31Normalize floating point negative zero to positive zero in `flodivmod'.Yukihiro "Matz" Matsumoto

2019-05-21Update ISO section number for some Numeric methods.Yukihiro "Matz" Matsumoto
2019-05-21Export `mrb_int_value` that converts `mrb_float` to `Fixnum`.Yukihiro "Matz" Matsumoto
Or `Float` if `mrb_float` value is too big (or too small) to fit in `mrb_int`. The `_int_` in `mrb_int_value` means `Integral` module, which represents integer-like values in mruby.
2019-05-21Silence the return value warnings from gcc; ref 237a57bYukihiro "Matz" Matsumoto
2019-05-21Move `**`,`/`,`quo`,`div` and comparison methods to Integral from NumericKOBAYASHI Shuji
Having these methods in Numeric can get in the way of creating subclasses of Numeric because they only support Fixnum and Float.
