Comment(by maxime.curi...@…):
The problem seems to be more of a general difference between ruby 1.8 and
ruby 1.9, than a MacRuby-specific problem:
# ruby -v => ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0]
{{{
>> require 'bigdecimal/math'
=> true
>> BigMath.methods.include? :sqrt
=> false
}}}
# ruby -v => ruby 1.9.2dev (2010-01-26 trunk 26419) [i386-darwin10.2.0]
{{{
>> require 'bigdecimal/math'
=> true
>> BigMath.methods.include? :sqrt
=> false
}}}
#macruby -v => MacRuby version 0.6 (ruby 1.9.0) [universal-darwin10.0,
i386]
{{{
>> require 'bigdecimal/math'
=> true
>> BigMath.methods.include? :sqrt
=> false
}}}
Since we are aiming to match Ruby 1.9's behavior, this is definitely
something that should be fixed. In the mean time, users can go around the
problem by:[[BR]]
- either adding 'include BigMath' after "require 'bigdecimal/math'"[[BR]]
- or using the instance method #sqrt on the object (i.e.
"four.sqrt(10)")[[BR]]
