How can I check that?

How can I check if a number is approximately equal to the other? I've been searching for 2 days and I didn't find any post that could help me, so either i'm blind or there aren't much topics about that.
I thought about (Z - Y) < 5 but I don't think it's the best way to do that... maybe.

Re: How can I check that?

Unless I misunderstand what you mean by "approximately equal", then (Z - Y) < 5 is exactly what you should be doing.

Approximately equal = almost the same

Someone correct me if I'm wrong but,

PHP Code:


		
			
X = 5 Y = 3 criteria : < 1

5 - 3 = 2 < 1 = false
3 - 5 = -2 < 1 = true

I think he has to use abs() on X - Y before comparing it.

Re: How can I check that?

Seems that my first idea was correct then, but I think I should make something more "universal". Like: If X value is 90% of the Y value is better, isn't it?

Let's suppose that we have 100 as X and 95 as Y, then we've 95% of the main value, so it's kinda approximated, or is it the same idea as doing X - Y < 5?

Re: How can I check that?

What do you mean with the same ? Closer to each other?

Are you using floats ?

Then use floatround..

Can you explain what are you doing this for?

Also pick out a better title for your thing.

Edit : best thing is to use your first thing no need to overcomplicate a simple thing

Re: How can I check that?

How about this?

This will check if iValueToCheck is >= fVariance percent of iCompareToValue.

PHP Code:


		
			
public plugin_init() 

{

    server_print( "Is 95 >= 90%% of 100? = %s" , AlmostTheSame( 100 , 95 , 90.0 ) ? "Yes" : "No" );

}



bool:AlmostTheSame( const iCompareToValue , const iValueToCheck , Float:fVariance )

{

    return bool:( ( float( iValueToCheck ) / float( iCompareToValue ) * 100.0 ) >= fVariance );

}

Code:

Is 95 >= 90% of 100? = Yes



Is 88 >= 90% of 100? = No

v
76
15 30 NE 60 75 E 105 120 SE

So, I asked that because if i'm looking at the direction 76, the next ones will be 91, 106, 121, etc... so with the approximate value, I could change the 91 or 106 to 90 and 105, y'know?

Is 88 >= 90% of 100? = No

I will roger that.

Edit:

Worked, thank you guys, specially Bugsy.

Re: How can I check that?

In that case you just should align your current angle to an increment of 15.

Code:

new const alignedAngle = (floatround(currentAngle + 7.5) / 15) * 15;

Then you can just add or sub 15 a couple of times to get 90, 105 etc.

And please set a proper title.

Re: How can I check that?

I'm not bumping, since I already solved it, I'm just answering KliPPy's reply:

That's what I'm doing:

PHP Code:


		
			
    iLocationNumber[0] = iCurrentAngle
    iLocationNumber[1] = iLocationNumber[0] + 15
    iLocationNumber[2] = iLocationNumber[1] + 15
    iLocationNumber[3] = iLocationNumber[2] + 15
    iLocationNumber[4] = iLocationNumber[3] + 15
    iLocationNumber[5] = iLocationNumber[4] + 15
    iLocationNumber[6] = iLocationNumber[5] + 15
    iLocationNumber[7] = iLocationNumber[6] + 15
    iLocationNumber[8] = iLocationNumber[7] + 15
    iLocationNumber[9] = iLocationNumber[8] + 15

Also, isn't your formula wrong? Like, lets say that currentAngle is 175, so it'll be:

floatround(175.0 + 7.5) = 182.0
182.0 / 15 = 12.13
12.13 * 15 = 182.0 ??

Did I misunderstand it?
