Description:
------------
When you use the range function, with a range between zero and 1, incrementing by 0.05 each step, the loop produces an incorrect result when you attempt to minus the current value in the loop from 1.

As you can see below, the last element in the array is the integer 1. The script should echo the result of 1 minus 1. However, for some reason PHP treats 1-1 as -2.22044604925E-16 instead of zero.

Reproduce code:
---------------
foreach (range(0,1,0.05) as $t)
	{
	echo (1-$t).'<br />';
	}

Expected result:
----------------
1
0.95
0.9
0.85
0.8
0.75
0.7
0.65
0.6
0.55

0.45
0.4
0.35
0.3
0.25
0.2
0.15
0.1
0.05

Actual result:
--------------
