Round floating numbers using XtScript round function

- Code: 
<!--parser:xtscript-->
	var $number = 7125.64559
	var $number_2 = 14.55

	# Round number to two floating decimal
	var $tdf = call round $num=$number; $precision=2

	# The precision can also be a negative number which will round number beyond the floating decimal
	var $neg_tdf = call round $num=$number; $precision=-2

	print Number: $number <br/>
	print Rounded two floating digit: $tdf <br/>
	print Rounded beyond the floating decimal: $neg_tdf

	print <br/><br/>

	print Second number: $number_2 <br/>

	print Round second number half to odd:
	call round $num=$number_2; $mode=PHP_ROUND_HALF_ODD; $precision=1

	print <br/>

	print Round second number half to even:
	call round $num=$number_2; $mode=PHP_ROUND_HALF_EVEN; $precision=1
<!--/parser:xtscript-->
- Result:
Number: 7125.64559
Rounded two floating digit: 7125.65
Rounded beyond the floating decimal: 7100

Second number: 14.55
Round second number half to odd:14.5
Round second number half to even:14.6
