Rounds a float
(PHP 4, PHP 5)
float round ( float val [, int precision] )
Returns the rounded value of val to specified precision (number of digits after the decimal point). precision can also be negative or zero (default).
Note:
PHP doesn't handle strings like "12,300.2" correctly
by default. See converting from strings.
Note:
The precision parameter was introduced in PHP 4.
