I often need to use fractional modificators for my variables. Like this:
JavaScript
x
$var *= 1.5;
Yet I need the oputput to be rounded, so I need to use:
JavaScript
$var = round($var * 1.5);
Is is no big deal, but every single time I can not use the *=
operator, and I need to write round()
. Is there a shrotcut for this?

Answer
As $var *= 1.5;
is a shortcut for $var = $var * 1.5;
this means that you can’t inject any function call here. So, $var = round($var * 1.5);
cannot be changed using *=
notation.
As a solution you can use a user-defined function:
JavaScript
$var = multiplyAndRound($var, 1.5);
function multiplyAndRound($var, $multiplier) {
return round($var * $multiplier);
}
// or with passing by refrence
$var = 1.3;
multiplyAndRound($var, 1.5);
function multiplyAndRound(&$var, $multiplier) {
$var = round($var * $multiplier);
}
But I don’t think that this can be called “shortcut”.
