Sent / Received Difference in networking and internet application

Following simple operation of addition using calculator in different operating systems in computer, mobile phones etc will give the reason for these difference send and receive data differences in networking and other communication devices:

1.577+1.433 = 3.01

2.677 +1.333 = 4.01

This result help to substitute a many different values to keep the result same for any addition involved functions in assembly and programming languages. In simple sense a security threat for any kind of character set where ever a base functions like addition, repetitive addition etc.. involved in any kind of application using such a device.  

Do this kind of maths manfully without using calculators in operating systems to see a different answer. Irrespective of the explanation for the result following can be a threat to traced to hard wares, asselmbly language, base calculator, operating systems, and software applications.
