Hi

For the purpose of naming a variable in a computer program, what is the correct word that describes both parts of a fraction?

e.g. a/b

a = numerator

b = denominator

a & b = ?

Hi Jibba Jabba;

Variables are usually given names that tell what they do. What does a / b do in your program?

Or do you want to know what the math name for a / b is?

Hi bobbym

Thanks for your quick reply.

I'm using the variable to store the lowest numerical value of a and b.

If, let a = 1 and b = 2. Then lowestValue = 1

So I'm looking for a noun, 'the math name', that describes both a and b. i.e. lowestMathName

The minimum is the closest math term. Is this for yourself or for an assignment?

For myself. I'm a self taught software dev enthusiast. I'm not a student of any kind except self ed.

Thanks for your answer.

That really surprises me you know. You've got numerator, denom, quotient etc but no common name for the 2 values to share. Wow.

I'll have to name it something like lowestValue, a bit general, or lowerValueOfNumeratorDenominator, too long. That's a bit ruff. Or i'll have to make a name up but no one will know what it means.

minimum is too general. Any ideas?

This is my 1st post. Looks like a great forum. My Math level is a rusty High School grad level.

The whole thing a / b is called a rational number or a fraction. That is a very general statement much like saying you and I are humans. Tells you alot about us but might make it difficult to tell us apart. You have chosen Jibba Jabba as your username. You did it for a purpose. Perhaps it reminds you of something you do not want to forget. Do the same with the variable name. In programming a good variable name helps you remember what the variable does.

I do not think you will have much problems naming it, after all you did come up with Jibba Jabba. By the way, welcome to the forum.

hi Jibba Jabba

**Welcome to the forum.**

i'll have to make a name up but no one will know what it means.

This happens a lot in maths. But you're supposed to define your terms so others do know what you're talking about.

eg.

If I meet a new term I look it up on
