PHP round precision bug?

Is this a bug or some math thing I don't understand?

round(58.900662, 2) => 58.9

Where is the last zero?

EDIT: In my opinion, the documentation is lacking information.

The following code does as expected

number_format(round(58.900662, 2), 2) => 58.90

round will take care of the precision if that digit is not 0 as the last 0 has no effect in any mathematical operation.

If the number is 1.569 then round will return 1.57

If you want that 0 the you can use - 

number_format(58.900662, 2, '.', ',');

number_format()

You told it to round it to the 2nd decimal place which would be 58.90. However, 58.90 can be simplified to 58.9. It is the same number.

If you want to force the display of two decimal places you can use PHP's number_format() function.
