in what languages it isn't?

$ python
Python 2.5.1 (r251:54863, May 12 2007, 11:15:25)
[GCC 4.0.1 (Apple Computer, Inc. build 5363)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> 1/100
0

(and C too, though I won't write the program here).

anyway, you can have 1/100 return a rational:

$ irb
irb(main):001:0> require 'mathn'
=> true
irb(main):002:0> 1/100
=> 1/100
irb(main):003:0> (1/100).denominator
=> 100
