2012-05-21 01:21:13 +0200	marked best answer	decimal form of a unit converted answer It is better to write the units to convert in decimal form `#define units ft = units.length.foot m = units.length.meter #add some lengths and output in ft (3.0ft+4.0m).convert(units.length.foot)`

2012-05-20 17:52:06 +0200	asked a question	decimal form of a unit converted answer I was wondering what a good way might be to get a decimal answer when using units. For example, say I try `#define units ft = units.length.foot m = units.length.meter #add some lengths and output in ft (3ft + 4m).convert(units.length.ft)` I get back `6143/381foot` Now, suppose I'd rather see this represented as a decimal than a fraction (for homework, perhaps?). If I try `(3ft + 4*m).convert(units.length.foot).n()` I get an error. This is occuring on Sage 4.8 for sure, and I'm pretty sure in Sage 5.0 as well. Can anyone think of a good solution to this?
