It can't.  But you just modified 1.5 into 1.50, which (given that they
aren't floating-point numbers) is an important difference.  Remember:
there can be more than one '.' in a version string.

Version strings aren't decimal numbers.
Most projects use each field as a separate integer.

1.1
1.2
1.3
1.4
1.5
1.6
1.7
1.8
1.9
1.10
1.11
1.12
1.13
1.14
1.15
.

.
1.49
1.50
1.51

So: 
14 is bigger than 5.

Really.
