Alright so I just ran into this issue. My problem is that the numbers/strings in question having varying numbers of digits. Some have no decimals, others have several. So for me, using int, float, double, intval, or floatval all gave me different results depending on the number.

So, simple solution... divide the string by 1. This forces it to a number and retains all digits while trimming unnecessary 0's. It's not pretty, but it works.

"your number string" / 1

Input       Output
"17"        17
"84.874"    84.874
".00234"    .00234
".123000"   .123
"032"       32

So, simple solution... divide the string by 1 server-side. This forces it to a number and retains all digits while trimming unnecessary 0's. It's not pretty, but it works.
