Bug #19335

Updated by kyanagi (Kouhei Yanagita) over 1 year ago

Thinking of the result of the following, `Integer#remainder` and `Numeric#remainder` should respect `#coerce`. 
 (`BigDecimal#remainder` seems to respect `#coerce`.) 

 ```Ruby 
 c = Object.new 
 def c.coerce(other) 
   [other, 10] 
 end 

 p 1234 / c            # => 123 
 p 1234.div(c)         # => 123 
 p 1234.quo(c)         # => (617/5) 
 p 1234.fdiv(c)        # => 123.4 
 p 1234 % c            # => 4 
 p 1234.modulo(c)      # => 4 
 p 1234.divmod(c)      # => [123, 4] 
 p 1234.remainder(c) # => in `remainder': comparison of Object with 0 failed (ArgumentError) 

 p 1234.0 / c            # => 123.4 123 
 p 1234.0.div(c)         # => 123 
 p 1234.0.quo(c)         # => 123.4 (617/5) 
 p 1234.0.fdiv(c)        # => 123.4 
 p 1234.0 % c            # => 4.0 4 
 p 1234.0.modulo(c)      # => 4.0 4 
 p 1234.0.divmod(c)      # => [123, 4.0] 4] 
 p 1234.0.remainder(c) # => in `remainder': comparison of Object with 0 failed (ArgumentError) 

 require 'bigdecimal' 
 p BigDecimal('1234.0').remainder(c) # => 0.4e1 
 ```
