string representation of mpq wihich are integers about gmpy HOT 9 CLOSED

Mario,

The change was an error on my part. mpq is supposed to behave just like 
Fraction. I'll create tags/gmpy_1_13 with the fix in a day or two.

Thanks for the bug report.

Thanks.

> mpq is supposed to behave just like Fraction.

Another difference between the two is
>>> a = mpq(1,3)
>>> print a.numer()
1

>>> b = Fraction(1,3)
>>> print b.numerator
1

similarly for the denominator.
Is it possible to add to gmpy.mpq something like

numerator = property(numer)

to allow the same call for both?

Mario

I've committed tags/gmpy_1_13 and it should fix the formatting. I also added 
improved caching for mpq types. I'm curious if you notice any performance 
improvements.

I'll work on adding .numerator etc. next.

Case

Thank you.

With version 1.13 I get 1-3% speedup.

Mario

I've added .numerator and .denominator to 1.13.

How soon do need this version officially released?

Great!

Mario

1.13 is officially released.

Mario,

While running some additional tests, I think my fix has a problem. Below is the 
behaviour of the Fractions module, gmpy, and gmpy2 (development branch).

>>> from fractions import Fraction
>>> str(Fraction(3,1))
'3'
>>> repr(Fraction(3,1))
'Fraction(3, 1)'
>>> from gmpy import mpq
>>> str(mpq(3,1))
'3'
>>> repr(mpq(3,1))
'mpq(3)'
>>> from gmpy2 import mpq
>>> str(mpq(3,1))
'3'
>>> repr(mpq(3,1))
'mpq(3,1)

Right now, gmpy 1.13 doesn't display the denominator of 1 even with repr. (The 
earlier bug displayed a denominator of 1 in all cases.) I'm planning a 1.14 
release within a few weeks. Will you have any problems if I use the gmpy2 
formatting rules since they match Fraction's?

Hi,

str(mpq(3,1))

 is quite fine.
