Strange Conversion?

[tsaiid]

ruby (2.1.2)
ruby-units (1.4.5)

2.1.2 :019 > Unit("1 mm") >> 'cm'
 => 1/10 cm
2.1.2 :020 > Unit("1.0 mm") >> 'cm'
 => 1/10 cm
2.1.2 :021 > Unit("1.1 mm") >> 'cm'
 => 0.11 cm
2.1.2 :022 > Unit("11 mm") >> 'cm'
 => 11/10 cm
2.1.2 :023 > Unit("111 mm") >> 'cm'
 => 111/10 cm

The result sometimes became rational. How can I force it not to be rational?

the version you are using uses rational numbers internally to avoid rounding problems. Why do you want to force it to not be a rational?

I have the same issue.

2.0.0p247 :030 > unit = Unit('1 oz') >> 'g'
=> 45359237/1600000 g

I would much rather get 28.3495231 g (at least for decimal units).

2.0.0p247 :040 > unit.scalar.to_f
=> 28.349523125

Any thoughts?

I am also seeing

2.0.0p247 :058 > Unit.new('1 1/2 oz')
=> 3/2 oz

Correct but now very user friendly, can you offer me any advise?
