Comment:
I commited an updated version of bigdecimal/math with r4202, but for some
reason, get NaN when I include both `bigdecimal` and `bigdecimal/math`,
but not if I include any of them:
{{{
$> macruby -r bigdecimal/math -e 'p BigDecimal.new("2").sqrt(10)'
#<BigDecimal:2000f15a0,'0.1414213562 3730950488 016887185E1',32(32)>
$> macruby -r bigdecimal -e 'p BigDecimal.new("2").sqrt(10)'
#<BigDecimal:2000e0aa0,'0.1414213562 3730950488 016887185E1',32(32)>
$> macruby -r bigdecimal -r bigdecimal/math -e 'p
BigDecimal.new("2").sqrt(10)'
#<BigDecimal:2000d0660,'NaN',4(32)>
}}}
