could you check this code, please?
 Quote: function Fractionizer(decimal as double) as string dim x, y, a, b as integer 'a and b are auxiliars y=10^len(right(decimal,len(decimal)-instr(decimal,".")) x=val(right(decimal,len(decimal)-instr(decimal,".")) a = x b = y while x<>y if x > y then x=x-y if x < y then y=y-x wend Fractionizer = cstr(a/x) + " / " + cstr(b/x) end function

I tested and it worked with small decimals, any suggestion?

Try this function (slighty changed)
 Code: function Fractionizer(decimal as double) as string dim x, y, a, b as integer 'a and b are auxiliars y=10^len(right(decimal,len(decimal)-instr(decimal,".")) 'x=val(right(decimal,len(decimal)-instr(decimal,".")) x= decimal*y 'changed 'a=x  changed a = decimal*y b = y while x<>y if x > y then x=x-y if x < y then y=y-x wend Fractionizer = cstr(a/x) + " / " + cstr(b/x) end function

and says me if this is what you want ?

I was getting some overflow problems so I changed ( in RED ), the data type from x, y, a, b from integer to double

 Quote: function Fractionizer(decimal as double) as string dim x, y, a, b as double 'a and b are auxiliars y=10^len(right(decimal,len(decimal)-instr(decimal,".")) x= decimal*y 'changed, you were right a=x ' not changed, 'cause is the same with less code b = y while x<>y if x > y then x=x-y if x < y then y=y-x wend Fractionizer = cstr(a/x) + " / " + cstr(b/x) end function

Unfortunately, I am out of town at the moment so I can only work from memory, but I am surprised that you do not simply pull the complete working example that already exists. That said, I also know the value of "rolling your own".

Let me ask a question since I can not run and test the code. What toes the following line of code really do?
 Code: dim x, y, a, b as double

If you said that this line of code declares three variables of type variant and one variable of type double then you are correct. Remember to declare the type for each individual variable.
