Your Answer for Question 1:
Since anything can be expressed in 0, and 1 the code of anything program is just nothing but that.  If someone would find out how the 0 and 1 were used, ie know what they represent, then they can change that binary to whatever they desire.  I assume you can put encrpytion in your code, but as we all know nothing is uncrackable since data can be anything.

Your Answer for Question 2:
A subnormal numbers are non-zero numbers who's magnitude is less than the overflow.  The are the numbers that can't be represented in float point that fills the gap between 0 and the smaller normal number.

Your Answer for Question 3:
The first one checks if x is a float point or not but the second one assume x to be an integer.

Your Answer for Question 4:
IEEE 754 has it's advantages because with 32 more bits for the significand it can represent numbers with better precision and size.  But your math co-processor might need need numbers in that kind of magnitude.
