php round bug
If you use the round function in php, it might get tricky because of the following:
echo round(3.1234, 2);
Will print 3.12, but, for example if you have the following:
echo round(3.1000, 2);
Will print 3.1 instead of 3.10. Even if you use the round function with two decimals php will automatically correct the result because 3.1 = 3.10.
In order to get rid of this you will need to use the number_format function as in the example below:
echo number_format(round(3.1000, 2), 2, '.', ',');
This code will print 3.10 instead of 3.1.
From my point of view this is a clear bug because 3.1000 rounded with 2 decimal precision is not 3.1, it’s clearly 3.10.
