How to convert decimal to whole number??

#1

%tempdist = mFloor(vectorDist(%playerposition, %botpos));

This simply always rounds down to the nearest integer value, so 90.9999 becomes 90 instead of 91.

%tempdist = mCeil(vectorDist(%playerposition, %botpos));

This always rounds up, so 90.00001 is 91.

#2 The old Tribes 2 RPG Mod had a mathematical function for rounding numbers using standard math. Here's the implementation of it:

function round(%n) {
   if(%n < 0) {
      %t = -1;
      %n = -%n;
   }	
   else if(%n >= 0) {
      %t = 1;
   }

   %f = mfloor(%n);
   %a = %n - %f;
   if(%a < 0.5) {
      %b = 0;
   }
   else if(%a >= 0.5) {
      %b = 1;
   }

   return mfloor((%f + %b) * %t);
}

#3 Great thanks guys.... works great!! One quick question, is this value in yards, meters, feet???

#4 Maybe we should add an mround() to the engine. We're already making two calls to mfloor() there so it would have to be faster to just make one call....

#5 I thought there was an mRound in the engine. Although i think i saw a post of it being broken. It was either working like Floor or Ceil I cant remember which.

#6 iirc mround is in the engine.

Should be in meters.

#7 Meters? What on Earth for? It's just a number rounding function, not a world unit conversion tool....

And it is there - for some reason Torsion didn't want to act like it was though - (in engine/math/mConsoleFunctions.cpp):

DefineConsoleFunction( mRound, S32, ( F32 v ),,
    "Round v to the nearest integer.n"
    "@param v Number to convert to integer."
    "@returns Number converted to integer."
    "@ingroup Math" )
{
   return (S32)mFloor( v + 0.5f );
}

Guess that's one way to do it....

EDIT
Looks like they all work, too:

%i = 1.6;
echo(" -- floor " @ %i @ " : " @ mFloor(%i));
echo(" -- ceiling " @ %i @ " : " @ mCeil(%i));
echo(" -- round " @ %i @ " : " @ mRound(%i));

produced

Quote:
-- floor 1.6 : 1
-- ceiling 1.6 : 2
-- round 1.6 : 2

in the console.

#8 very cool... thanks guys!!

#9 @Richard, I took it as what is the torque unit or whatever the coordinate system is based upon considering his above code had vectors, not actually dealing with the mRound :P

#10 jeffs right, I only meant torque unit, sorry for the confusion. mRound works great and nice to know thanks everyone....

#11 See? I told you guys I never pay attention in class....

#12 I thought there was an mRound in the engine.
