Perl does lots of magic, especially in the way it handles scalars as strings, integers and floats simultaneously.<p>
In your case, the value is being handled as a string until you force Perl to treat it as a number (by using it in a multiplication). The result is a floating point value, subject to the inaccuracies described elsewhere. If it comes up with a seemingly exact value sometimes, well, welcome to the mystery :)<p>
I take it the issue here is that you want a leading zero, or some other normalization? If so, then use sprintf to enforce the format you want. Try <code><%=sprintf("%1.2f",$target)%></code> for instance.
