Hi, how can I'm convert 4.93802935 to 4.39...I'm thinking like's strfind(4.93802935,"(%x+.%x)")

More efficient:

function Round(iNumber)
   assert(type(iNumber) == "number");
   return floor( iNumber + 0.5 );
end

Round is designed to round the first place after the decimal. So you would use:

local myNumber = 4.93802935;
myNumber = Round( mNumber * 100 ) / 100;

Just presenting concept here. Haven't actually tested.

10x u :D

what about:

   myNimber =  4.93802935
   myNimber = format("%0.2f", myNimber )

u will get 4.93

[NotRabidWombat]

Yes that will also work. However the return result is a string. I was assuming he wanted rounding rather than truncation.

local myNumber = 4.93802935
myNumber= format("%0.2f", myNumber)

you will get (and I typed it wrong) 4.94

local myNumber = 4.93328029
myNumber= format("%0.2f", myNumber)

you will get 4.93


and round() is not a Lua interface

[NotRabidWombat]

Ah cool. Did not know format would handle that.

"and round() is not a Lua interface"

I don't understand your point. It's a function that I just wrote.
