Remove trailing zeros in decimal value with changing length

Question

I have a procedure I am doing that displays odds but the client wants only significant digits to be shown. So, 1.50 would show as \'1.5\' and 1.00 would show as \'1\'.

Answer 1

If you are using PHP as the scripting language you may use the following:

$var = (float)$var_having_extra_0; // $var = (float) 17.5000

Or use the PHP floatval function:

$var = floatval($var_having_extra_0); // $var = floatval(17.5000)
