Description

The following code:

<?php
  printf("%.f\n", 3.1415926535);
  printf("%.0f\n", 3.1415926535);
  printf("%.6f\n", 3.1415926535);
?>

Resulted in this output:

3.141593
3
3.141593

But I expected this output instead:

3
3
3.141593

because the documentation (https://www.php.net/manual/en/function.printf.php and https://www.php.net/manual/en/function.sprintf.php) says "Note: If the period is specified without an explicit value for precision, 0 is assumed."
