rounding a decimal

@batteries - thanks.

Also, to display 3.30 rather than 3.3 try this:

Code:

$y = 5.9999;  // number to round down
$p = 2;  // number of decimals
$n = pow(10,$p);  // multiplier and divisor
$x = sprintf("#01.${p}f", floor($y*$n/$n));  // result is a string

which could be made into a function if needed more than once.

Edit: replace the # with % in the sprintf function above ... forum software wouldn't allow a % there apparently.
