2018-09-19Remove 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).

2017-08-22Remove possible path that leaves a local variable uninitialized.Yukihiro "Matz" Matsumoto
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.
