in reply to Re: Rounding off numbers
in thread Rounding off numbers

.. though it's important to remember that simply casting a float to an int, thus:
my $float = 2.744; my $int = int $float;
results in the decimal part of the number simply being truncated, giving an integer value with the above example of 2, not 3, which is possibly not what's expected.

Update: Although, of course, adding the 0.5 to the number solves the problem nicely. Didn't see that in the post until just now ..
