[SOLVED] Why doesn't the 'int' function return an integer value?

@Warfley
You didn't comment the picture of Microsoft calculator. It thinks that round(2.5) = 3, BTW

This is not for restarting the discussion, but I think it's worth to note.

From ISO 7185 Pascal (point 6.6.6.3) and ISO 10206 Extended Pascal (6.7.6.3):

round(x)
From the expression x that shall be of real-type, this function shall return a result of integer-type.
If x is positive or zero, round(x) shall be equivalent to trunc(x+0.5); otherwise, round(x)
shall be equivalent to trunc(x-0.5).

And indeed, in modes ISO and ExtendedPascal the result of round(2.5) is 3.

When I first read the original post I thought that the question was... why is the function called "Int"; couldn't it be better named so as to avoid bugs when you don't "think" that you have to RTFM.

NOTE: I am NOT saying this. I am saying that this is how I interpreted the original question after a quick scan of the title.
