How Can You Simplify Decimal Notation in PHP by Removing Redundant Zeroes?

Simplifying Decimal Notation by Removing Redundant Zeroes

Eliminating trailing zeroes from decimal numbers can offer visual clarity and simplify calculations. In PHP, a straightforward solution exists to achieve this objective:

<code class="php">$num + 0;</code>

Utilizing this expression with numeric or string variables effectively strips away any redundant zeroes:

<code class="php">echo 125.00 + 0; // Output: 125
echo '125.00' + 0; // Output: 125
echo 966.70 + 0; // Output: 966.7</code>

Internally, PHP interprets this expression as a conversion to float, which can also be accomplished using the floatval() function or the (float) cast. Nonetheless, the addition operator provides a more concise and intuitive approach.

It's worth noting that negative numbers will retain their trailing zeroes, preserving accuracy for such scenarios.
