Fractions in Visual Basic.Net

Desi Bravo

I appreciate for your time. I am an intermediate programmer, I am not an expert like you. So being trivial I really dont think so in my part. I am trying to learn this solution. I enter a numerator and denominator in the textboxes. There is no text to convert. Trying to figure out how to use the numerator and denominator in a fractional sense in a program. Don't know if i would use the abs or just something else to get the result in the label as a fraction.

I appreciate for your help, but I already know to convert a fraction to a decimal. The code is related only to fraction conversion to decimal. I would need to know how to render an answer in fraction not decimal. For instance, 5/8 + 1/8 = 6/8 reduces to 3/4. So therefore, the textbox1 will be the numerator and textbox2 will be denominator. The third textbox will return the fractional value. Or textbox3 will be the numerator and textbox4 will be the denominator and this will invoke the answer. I am having the problem of generating a code for the above instance in fractions. bravo659

ah, but you never said you wanted to make a formal calculus... i never searched for that exactly, but looking at some math parsers here on CP should help you to achieve your goal. moreover, don't 5/8 + 1/8 make 6/8 ??? :-D anyway, nevermind, i won't repeat it :laugh:

It's only an example. In a tape measure would be 3/4 of an inch. And Yes, it would also be 6/8 but reduce it to the LCD would be 3/4. That's the only problem that I am having, using the fractional portion to render an answer in fractions. There is a site called Break Tru, and they are selling a fraction and decimal program, but can't get the code for that program. For what I want it for is for several fraction programs. Does your home have heat oil. Then you would know that the tank only reads in fractions. I created a program that will give you how much oil you have in your tank and the amount you need to refill it, and how much it will cost you, and the amount of tax and a grand total. I also added on the form a fraction to decimal converter, which is the only i can offer under that program because I don't know how to render the fraction resulting in fractions. If you know of anything or a book that I can purchase in algorithm please let me know. I am up to programing almost in calculus. LOL Thanks Bro for your help.

If you go to Jesse Liberty's site http://www.libertyassociates.com/pages/book_edit.htm[^] and download the source code for Programming C# 3rd edition then you'll find a (simplified) Fraction class that you could perhaps adapt for your purposes. It's in the Ch 6 folder. Kevin

Re: Jesse Liberty - Programming C# - he has a VB .NET version of the same book with source code so you could download the source for that one instead. Kevin

This sounds more like an issue with Math than it is VB .NET X| It's just a matter of making the right calculations to display the appropriate whole number.

Desi Bravo

Oh no, i know how to calculate fractions without a problem, is that how do you use the textboxes to display fractions. That's the problem. I've seen it done through C#, but I tried to use it in VB.Net, and it doesn't work. So the solution is in progrmming in VB.Net. That's all. I appreciate for your feedback.

I appreciate for your info. I'll try Jesse's book. bravo659

There is nothing in the Math namespace to show fractions as fractions. You need to convert to numbers, work out a whole number part, and render it all as text yourself. Christian Graus - Microsoft MVP - C++
