KOBAYASHI Shuji 6e2edd8ed2 Add mrb_noreturn to cmperr() in src/numeric.c 2019-08-06 23:04:40 +09:00
KOBAYASHI Shuji 334afb167c Use new specifiers/modifiers of mrb_vfromat() 
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.

BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613,
so I put it back.

Yukihiro "Matz" Matsumoto 96ac49b75b Avoid MRB_INT_MIN to apply fixdivmod. 
`MRB_INT_MIN` is the only integer value that has no corresponding
positive integer value (i.e. `-MRB_INT_MIN` = `MRB_INT_MIN`).

Yukihiro "Matz" Matsumoto e941cf06a3 Export mrb_int_value that converts mrb_float to Fixnum. 
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.

KOBAYASHI Shuji 3b46831da8 Move **,/,quo,div and comparison methods to Integral from Numeric 
Having these methods in Numeric can get in the way of creating subclasses of
Numeric because they only support Fixnum and Float.

Yukihiro "Matz" Matsumoto 8a9f984eb8 Add a new function mrb_int_value.

otherwise it returns `Float` value (mruby behavior of handling integers).

  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"

Yukihiro "Matz" Matsumoto e690314525 Recover #to_int; ref #4177 
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.
 2018-12-17 15:59:42 +09:00
Yukihiro "Matz" Matsumoto afca99a40b Remove implicit conversion using to_int method. 
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).
