I am trying to turn a number like this: 1.945753

into this: 1.945

or even this: 1.946

Is there a function or some mathematical process to do that in a script?

Try using http://www.creationkit.com/Floor_-_Math? Or http://www.creationkit.com/Ceiling_-_Math?

Huh? wiki on this page http://www.creationkit.com/Math_Script said:


int Function http://www.creationkit.com/Floor_-_Math(float afValue)

• Calculates the largestinteger less than or equal to the value.

I need a float not an integer.

1point945

not 1945

Is there a way to make numbers like 1point945787 into 1point945 or 1point946 ?

I do not want numbers like 1.945787969404 as notifications from my mod.

Perhaps something like this?

Float Function RoundFloatToXDecimalPlaces(Float MyFloat, Int DecPlaces)    Int Multiplier = Math.Pow(10, DecPlaces)    MyFloat *= Multiplier    Int Floored = Math.Floor(MyFloat)    if (MyFloat - Floored >= 0.5)        Return ((Floored + 1) / Multiplier) as Float    else        Return (Floored / Multiplier) as Float    endifEndEvent

What you're looking for is called 'truncation.'

Random's code should work well for it.

If you convert a number from float to integer, al floating part will be eliminated. Thus, if you as an example have the number 1.9392933332 and want to convert to something like 1.93 you can simly multiply the number by 100 convert to integer, convert again to float and divide by 100. You could also use this along floor and ceiling functions.

Funny as I did try that at first, but what I did not do was convert to an INT first.

MyFloat = MyFloat * 1000
MyFloat = floor(MyFloat)
MyFloat = MyFloat / 1000

did not work(that is when I posted here...)

So now I will try:


Int MyInt = (MyFloat * 1000) as Int
MyInt = floor(MyInt)
MyFloat = (MyInt / 1000) as float

Thanks!

I'd do it by using modulus ...

;Truncate to 3 decimalsmyFloat -= myFloat % 0.001;Round to 3 decimalsmyFloat += 0.0005myFloat -= myFloat % 0.001

Edit: Sorry but after trying this myself I acutally realized modulus in Papyrus wont work on non-integers. Limited !@#$%

... would give a result that's 1000 times what's expected.
