Rounding to nearest multiple - AMouldyLemon - 09.08.2016

I need an equation which returns the nearest value to a specified multiple. I've tried searching around the web but could only find either Rounding up or Down. I've been trying to find a solution to this problem for ~5 days, any help would be much appreciated, thanks.

A - Divide the number by the specified number (that you want it to be multiple of) (rather as a float/float so you would get precision)
B - Use floatround
C - multiply the number by specified number

Re: Rounding to nearest multiple - AMouldyLemon - 09.08.2016

That returns the nearest whole number.

Код:

public Align(Float:angle) {
	new Float:a = angle / 45;
	floatround(a);
	return a * 45;
}

EDIT:
It actually just prints the number given in the parameter. Ex: 34.4 prints 34.399999

Returns 0.0

Re: Rounding to nearest multiple - Nero_3D - 09.08.2016

some missing Float tags

PHP код:



Float: Align(Float: angle, Float: number = 45.0) {

    return floatround(angle / number) * number;

}

Thanks a lot!

floatround(a); doesn't change a to a rounded one, it returns one with rounded, so you would need to actually assign that value to something, like new temp=floatround(a);

PHP код:



public Align(Float:angle)

    return floatround(angle/45.0)*45;

Or if you want a more general function:

PHP код:



public Align(Float:angle, number=45)

{

    new num=floatround(angle/float(number));

    return num*number;

}

This gotta work, however note that most important part of that is the 45.0, because it makes it a float/float division so 34.4 would actually return 45 instead of 0
