Even numbers on randomly generated floats (Unity - C#)

[minibois]

Very basic and probably easy question, but I cant find an answer only and I can't think of anything now.

How can I make it so the random generated floats are even number? Or even in 0.5f increments?

 

The code that generates the numbers:

EnemyPositions = new Vector2(Random.Range(20.0f, 28.0f),Random.Range(-4.4f, 4.4f));

So it makes a random float between 20.0f and 28.0f and also another random float between -4.4f and 4.4f.

This is an example of floats that I get returned from this:

These are two sets of random generated floats and they are quite near each other in value

 

Thanks

I don't quite get it.

 

What is an even float number?

Something like 2.0? Is 2.1 even? Or is it something like 3.4 ?

 

Do you want to get random numbers varying with 0.5 ?

Should have explained, float is like a double or number variable. So a number which can have decimals (as opposed to Int for example, which can't have decimals) and it has an f behind it, since that variable is used in another sort of circumstance. Anyways

I want to make my random numbers without decimals (so the random number between 20.0f and 28.0f can only be 20.0f, 21.0f, 22.0f, etc.)

float has a dot . (and decimals)

int has no dot (and no decimals)

I know what floating point numbers are, I didn't get what you meant.

I understand now though.

You could generate a random int in your range and multiply it by 1.0f.

Or just convert that int to a float.

And if you want to do in increments of 0.5 , create a random int in double your range (for your example , [20.0, 28.0] would become [40.0,56.0]) then multiply it by 0.5f.

If you are not worried about rounding then just cast to an int. (this causes truncation e.g. numbers after the decimal point are discarded.)
