2022-07-12 14:48:36 +09:00
48b43af37f
numeric.c (mrb_div_int_value): should support integer overflow.
...
Especially in `MRB_INT_MIN/-1` which is bigger than MRB_INT_MAX.

e1980d7596
numeric.c (mrb_div_int): separate the function in two.
...
- mrb_div_int() does integer division in Ruby way (mdiv)
returns mrb_int
- mrb_div_int_value() division with zero div and overflow checks.
returns mrb_value
2022-07-09 14:38:18 +09:00

numeric.c: avoid mathematical operations for simple cases.
2022-07-09 10:45:11 +09:00
960021e519

numeric.c: mrb_float_to_integer can return a big integer.
2022-04-25 10:02:54 +09:00
0f4769536b
src/numeric.c: use mrb_ensure_float_type().
...
Instead of obsolete `mrb_to_float()` or the combination of
`mrb_float_value(mrb_as_float())`.
2022-04-25 07:29:55 +09:00
56a35131a4
numeric.c (mrb_cmp): should not raise NoMethodError.
...
Even when `obj1` does not have `<=>` method.
2022-04-24 14:02:00 +09:00
9dd45df804
numeric.c (int_pow): should not overflow.
2022-04-21 11:35:52 +09:00
b38a766427
numeric.c (flo_to_i): use bigint if the value is bigger than mrb_int.
2022-04-18 12:31:15 +09:00
c0ef940c90
numeric.c: add boundary checks in Float#to_f.
...
- check_num_exact() before rounding the float value
- check integer (mrb_int) overflow.
2022-04-17 09:32:04 +09:00
dcaf4083d5
src/bigint.c: implement multi-precision integer.
...
To enable multi-precision integer support, you need to link
`mruby-bigint` mrbgem. The gem itself is empty but it turns on
the "bigint" support.
2022-04-09 17:16:10 +09:00
5a27b69aa6
numeric.c: remove duplicated code in int_divmod.
2022-04-06 17:04:40 +09:00
5bef8e4135
numeric.c: the result of -5.div(2) should be -3 as CRuby does.
2022-04-06 17:04:40 +09:00
b99c389ec3
internal.h: aggregate internal functions.
...
Internal functions can only be called from within the library.
Functions listed in `mruby/internal.h` can be called from:
* core (src/*.c)
* gems (mrbgems/**/*.c)
But not from the application linked with `libmruby`.

...
No longer need to override division methods in mrbgems.
2022-03-18 12:27:46 +09:00
4dcdf78f8a
numeric_ext.c: add Integer#pow() method.
...
Which takes optional second argument of modulo.
2022-03-17 23:25:50 +09:00
6aa5d53867
numeric.c: avoid mrb_float with MRB_NO_FLOAT; fix #5671
...
`MRB_USE_COMPLEX` is exclusive with `MRB_NO_FLOAT`, so we only need to
check the former.
2022-03-15 19:07:28 +09:00
7659b3b271
numeric.c: avoid mrb_funcall; call functions directly.
...
When you try to call functions defined in mrbgems, you need to add the
names of functions to `mrbc.c`, since `mrbc` does not link any mrbgem
regardless of the configuration.
2022-03-12 13:31:38 +09:00

numops.c: separate API functions not used from mruby.

numeric.c: avoid implicit cast from integer to double.
2022-02-08 13:11:44 +09:00
b9e1b9b328
numeric.c: merge mrb_as_float implementation to mrb_ensure_float_type.
...
Since they are basically duplicated functionality. `mrb_as_float` is now
a macro defined using `mrb_ensure_float_type`; #5620
2021-12-31 15:14:37 +09:00
7f40b645d2
numeric.c: mrb_as_float should not call to_f for generic objects.
...
It should only call `to_f` for Rational and Complex numbers.

5a57602860
Organize the include of header files
...
- `#include <math.h>` is done in `mruby.h`.
Eliminate the need to worry about the `MRB_NO_FLOAT` macro.
- Include mruby header files before standard header files.
If the standard header file is already placed before `mruby.h`, the standard header file added in the future tends to be placed before `mruby.h`.
This change should some reduce the chances of macros that must be defined becoming undefined in C++ or including problematic header files in a particular mruby build configuration.

numeric.c: fix a bug in left shift of negative integer.
...
`-1 * (1<<63)` causes overflow, but `-1<<63` is a valid value.
2021-08-04 12:05:09 +09:00

b9d2b47f16
Replace mrb_fixnum_value() with mrb_int_value().
...
Use `mrb_fixnum_value()` only when you are absolutely sure that the
value is within `Fixnum` range, i.e. 31 bits signed integer at least.
2021-08-03 13:00:11 +09:00
23e7cb41e5
Replace fixnum references with int.
...
The `Fixnum` class is no longer provided by `mruby`.
2021-08-03 13:00:10 +09:00

8416e706ba
numeric.c: add optional ndigits argument to rounding methods.
...
- `truncate`
- `floor`
- `ceil`
`round` already takes `ndigits`.
2021-06-21 10:24:55 +09:00
7c8a91ff5a
numeric.c: restore fmt argument for backward compatibility.
...
`mrb_float_to_str()` used to take `fmt` argument. We thought no one used
the function, and OK to remove the argument. But at least `mruby-redis`
gem used the function.
