Hey guys, Im pretty new to turing and new to these boards and I am in need of help for a program that we wrote in class the other day. The teacher handed us a few problems and told us to write them up, we didnt have to, but they were extra practice. Anywho I got stumped on this one question. What we need to do is write a program (in turing of coarse) that will add 2 fractions that the user inputs and than outputs the answer. well that was easy, heres my code for it
code:  % All the program variables
var fTop, fBottom, sTop, sBottom : int
% Now getting the 2 fractions from user
put "Enter the first fraction (enter Numerator, space, enter denominator) " ..
get fTop, fBottom
put "Enter the second fraction (enter Numerator, space, enter denominator) " ..
get sTop, sBottom
% Spacer
put ""
% This will show the user their 2 fractions with a '+' between the 2
put fTop, "/", fBottom, " + ", sTop, "/", sBottom
% This will add the 2 fractions and output answer
put "= ", (fTop * sBottom) + (sTop * fBottom), "/", (fBottom * sBottom)

so say the user inputs 3/4 and 5/12 it would look like...
3/4 + 5/12 = 56/48
Now how would I write something to round the fraction? would i use IF statement... could somebody (if you have some free time) pelase write me what I would put for the program to round the fraction if the fraction could be rounded

no, you would use round(), it rounds up no matter what the decimal is, but if you want to round down... then you use floor()
ex:
code:  put round(24+15)
put floor(24+15)

but in this case you dont need to round an addition question, but thats how you would use it

i think i misunderstood the question... i thought he wanted to round the top number... so if he got 2.5/4 then he wanted it as 2/4(1/2) or 3/4 or something like that... you see what i mean?
