Hi,
Any suggestions on how to write an rspec expectation for equality when you
get a BigDecimal back. I see that "big_decimal_variable.should == 123.23"
doesn't work as the ruby BigDecimal comparison (via ==) to the same Float
value gives false (not true as you'd expect). For background / as an
example see below:
?> bd
=> #<BigDecimal:221832c,'-0.32303E3',8(12)>
>> f
=> -323.03
>> f.class
=> Float
>> bd.should == f
Spec::Expectations::ExpectationNotMetError: expected: -323.03,
got: #<BigDecimal:221832c,'-0.32303E3',8(12)> (using ==)
from
/opt/local/lib/ruby/gems/1.8/gems/rspec-1.1.11/lib/spec/expectations.rb:52:in

from (irb):73
>> bd == f
=> false
>> f == bd
=> false
thanks
