Bug #1454

Updated by shyouhei (Shyouhei Urabe) about 11 years ago

=begin 
  
  I did the following to produce this error: 
 
  --------------------------------------------- 
  ruby 1.8 
  --------------------------------------------- 
  require "rational" 
  require "bigdecimal" 
  a=BigDecimal("3.2") 
  b=Rational(3,4) 
  b/a 
  ---> TypeError: Rational can't be coerced into BigDecimal 
          from /usr/lib/ruby/1.8/rational.rb:206:in `coerce' 
          from /usr/lib/ruby/1.8/rational.rb:206:in `/' 
          from (irb):14 
 
  b+a, b-a and b*a yield a similar error 
  a+b, a-b, a*b and a/b work fine.

  --------------------------------------------- 
  jruby 1.2 
  --------------------------------------------- 
  jruby does seem to have this issue:
