roundTo()

Here's a function for rounding to different places (tenths place, hundredths place, etc etc)

PHP Code:


		
			
public function roundTo(val, place) {

  temp.tokens = val.tokenize(".");

  if (temp.tokens[1].substring(place, 1) < 5) temp.decimal = temp.tokens[1].substring(place);

  else if (temp.tokens[1].substring(place, 1) >= 5) temp.decimal = temp.tokens[1].substring(0, 1) + 1;

  temp.newval = temp.tokens[0] @ "." @ temp.decimal;

  return temp.newval

}

Example:

PHP Code:


		
			
temp.value = 10.56;

temp.newvalue = roundTo(temp.value, 1); //rounds to the tenths place, 2 would round to the hundredths place, 3 to the thousandths place, etc etc

echo(temp.newvalue);

would return "10.6."

Useful but this is a much shorter, simpler and overall less cpu-use way to do it:
(also supports more then just 0.1, 0.01, 0.001, etc.)

PHP Code:


		
			
public function roundTo(val, place) {
  return int(val/place + 0.5)*place;
}

Two examples:

PHP Code:


		
			
myvalue = 53.42;
roundTo(myvalue, 0.1);

myvalue would be 53.4

PHP Code:


		
			
myvalue = 53.463;
roundTo(myvalue, 0.05);

myvalue would be 53.45

Basically this just takes value and rounds it to the closest "place".

(Didn't see this thread till just now >_<)

Yea, I kind of wanted to say "Way to ruin someone's day" to Zero.

But oh well, now you are stronger.

This is part of the shared functions package, by the way.

They don't work on mobile servers sadly. But I remember adding a class with all shared functions to Era iPhone, not too sure if it's still around
