2019-05-20Add new functions for numerical operation; ref 237a57bYukihiro "Matz" Matsumoto
New functions: * mrb_num_plus(mrb, x, y) * mrb_num_minus(mrb, x, y) * num_num_mul(mrb, x, y)
2019-05-18Move `Numeric#__coerce_step_counter` to `Integral`KOBAYASHI Shuji
This method is only used in `Integral#step`
2019-05-17Make unused functions private.Yukihiro "Matz" Matsumoto
* mrb_fixnum_plus() * mrb_fixnum_minus() * mrb_fixnum_mul()
2019-05-17Remove unused `mrb_num_div()` function.Yukihiro "Matz" Matsumoto
2019-05-17Move `Numeric#div` to the core.Yukihiro "Matz" Matsumoto
2019-05-17Make `flo_rount` to return `Integeral`.Yukihiro "Matz" Matsumoto
2019-05-17Change the `num.divmod(float)` to return `[int,num]`.Yukihiro "Matz" Matsumoto
2019-05-17Add a new function `mrb_int_value`.Yukihiro "Matz" Matsumoto
This function returns `Fixnum` if the value fits in `mrb_int`, otherwise it returns `Float` value (mruby behavior of handling integers).
2019-05-17Use `int64_t` instead of `mrb_int` in `int64_value`.Yukihiro "Matz" Matsumoto
2019-05-16Terminate float right shift if shift value is too big.Yukihiro "Matz" Matsumoto
2019-05-02Unify overflow error class for conversion to integer to `RangeError`KOBAYASHI Shuji
2019-04-15Fixed wrong function names; fix #4380Yukihiro "Matz" Matsumoto
2019-04-08Fix C99 style inline declaration; fix #4365Yukihiro "Matz" Matsumoto
2019-03-21Fix `Float#eql?`KOBAYASHI Shuji
2019-01-16Avoid runtime evaluation for `MRB_WITHOUT_FLOAT`KOBAYASHI Shuji
2019-01-13Improve compatibility to CRuby for `Float#to_s`KOBAYASHI Shuji
Bfore: Float::INFINITY.to_s #=> "inf" 50.0.to_s #=> "50" 1e20.to_s #=> "1e+20" After / CRuby: Float::INFINITY.to_s #=> "Infinity" 50.0.to_s #=> "50.0" 1e20.to_s #=> "1.0e+20"
2019-01-10Remove duplicate code in numeric.cKOBAYASHI Shuji
2019-01-04Integrate mrblib/float.rb into src/numeric.cKOBAYASHI Shuji
- Avoid hack for `MRB_WITHOUT_FLOAT` in build scripts - Avoid runtime dispatch for `MRB_WITHOUT_FLOAT`
2018-12-17Recover `#to_int`; ref #4177Yukihiro "Matz" Matsumoto
We have removed implicit conversion to strings using `to_int`. But some users still using `to_int` as a typical integer method, i.e. they do string check by code like: `obj.respond_to?(:to_int)`. So we have recovered the method.
2018-11-19Remove implicit conversion using `to_int` method.Yukihiro "Matz" Matsumoto
The ISO standard does not include implicit type conversion using `to_int`. This implicit conversion often causes vulnerability. There will be no more attacks like #4120. In addition, we have added internal convenience method `__to_int` which does type check and conversion (from floats).

implicitly converted to 64 bits (was 64-bit shift intended?)

2017-08-10Remove redundant `flo_hash` function.Yukihiro "Matz" Matsumoto
`flo_hash` implemented `15.2.8.3.18` but `Kernel#hash` (15.3.1.3.15) now works for numbers.

They didn't work well with inexact numbers (inf,nan). Fix #3671
2017-05-26Add new range check macro FIXABLE_FLOAT(); ref #3652Yukihiro "Matz" Matsumoto
When MRB_INT64, valid value range of mrb_int is bigger than double, which only has 53 bits significant precision.
