Question

Say I have

$number = .20

When I go to run the script, PHP automatically removes the zero, leaving just .2. How can this be fixed?

I know that .2 and .20 are the same, but what I am using this number for, I need the zero.

Answer 1

The only think I can think of which requires the trailing 0s is displaying the number. .20 can be printed as follows:

// The number to display
$n = .2;

// The number of decimal places
$places = 2;

// Print the number to the desired precision.
echo number_format($n, $places)
