Thank you, fellow monks. While two of the above answers pointed out that int is exactly doing what its supposed to do, Rata followed the rather pragmatic approach to show how to actually use the int-function to get the expected result. Let me please try to hold awaken the interest in the practial approach, while peeking into the computer scientist material later.

In the following view on the problem, I try to round the number 1.255, and try to get the result 1.26. How would you perform this with the typical on-board means, to which undenyingly int() belongs to?

#!/usr/bin/perl
my $i = 1.255;
print int($i*100+.5)/100;
print "\n";

Please register, that the same code will do as expected when using "1.355" as value for $i.

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
