In general that's a very bad idea. If the number is larger, multiplying by 100.1 will severely skew the result: 
$ perl -wle ' my $x = 123456.15; print +(int($x*100.1))/100;'
123579.6

So it turned 123456.15 into 123579.6 just to get rid of rounding errors - and produced errors which are about a thousand times larger.

Instead you can add (not multiply) a small constant before calling int: 

$ $ perl -wle ' my $x = 1.15; print +(int($x*100 + 1e-8))/100;'
1.15

Depending on the range of the used numbers you'd have to think a bit more about the size of the small number you add.
