Comment(by hghoe...@…):
Replying to [comment:2 maxime.curi...@…]:
The "correct" way to check for sqrt in 1.87, 1.92 and macruby is
{{{
BigDecimal.method_defined? :sqrt
}}}
which returns true in ruby 1.87, ruby 1.92 and macruby.
In 1.87 and macruby you can call
{{{
result = BigDecimal.sqrt(..,..)
}}}
That doesn't work in 1.92. Here you call
{{{
result = BigMath.sqrt(..,..)
}}}
which also works in 1.87 and macruby. But
{{{
BigMath.method_defined? :sqrt
}}}
will return false in ruby 1.92, but true in 1.87 and macruby.
{{{
include BigMath
result = sqrt(..,..)
}}}
is working in all versions. This small changes are definitely confusing
and probably a bug in ruby 1.92.
But BigMath.sqrt is defined in macruby: calling sqrt doesn't raise a
NoMethodError, but returns NaN for any BigDecimal object.
