# how to get output in a mixed fraction?

regular rational sage style is like

sage:22/10

i want make it look like (thru pprint it will just look like a mixed on papper)

sage:2+2/10

is this possible?

If you want all rational numbers to look like this, then there isn't a convenient way to make that happen in Sage. I'm currently working on a framework to allow one to do this, but it's not ready yet. I will update this post when there is a ticket in question

However, if you just want a function that will return a string in the right form, you can use something like the following

def pprint(rational):
if rational < 0:
return '%s - %s'%(rational.ceil(), rational.ceil() - rational)
elif rational > 0:
return '%s + %s'%(rational.floor(), rational-rational.floor())
else:
return '0'

yeah would be great to deal this without that much complex constructions..

got an easier solution btw

sage: a=22/10 sage: floor(a), a - floor(a) (2, 1/5)

Note that if a is something like -22/10, that will give (-3, -4/5) which is probably not the desired result.
