Details:

Up to the latest 3.6.x version the statement
printf("%d...", x)
would format x as an integer, regardless if it in fact was a float. (So 3.4
would print as 3). This is the same behaviour as I would expect to see in any
other programming language as well.

Since version 4.0 the same statement will not round the number, it will print
a floating point value when x is not an integer. (So it now prints 3.4 as 3.4)
This causes my code to fail and is absolutely inconsistent with any
programming language I know.

Also I have been unable to find a format conversion that would in fact produce
the desired result.
