Hi. I have a somehow strange question.
I own a Casio calculator on which you can program in BASIC.
I'm searching for a program now which can make 12355/12354 out of 
1.000080945. I started to write a program where a/b=x.
I simply took the x-int(x) and multiplied it with n=1,2,3,4,...
just until the result y would be the same as int(y), an entire 
number. so the a would be n and the b would be y.
Unfortunately, this does only work with small numbers like 1.125.
As those calculators round the last bit of the number (as you can 
the with the first example, 1.000080945 * 12354 = 12354.99999),
so for some calculations it doesn't work, and for the rest it 
takes centuries. I woud have to make an aproximisation, but i 
don't know how.
If you have a similar program in BASIC (or in PASCAL, i could try 
to translate it), please send it to me. I would be very happy.

Thanx.
