Most floating point numbers (such as 5.35) aren't stored as exact values, just approximations. Use something like if ( abs($n1 - $n2) < 0.0001 ) { ... } to test for nearly equal.

Depending on what it is you're trying to test, you may be able to use >= or <= instead.

update:

google has many links you can read for more details.
