This Powerpoint covers 1.4.1 (g) - Representation and normalisation of floating point numbers in binary and 1.4.1 (h) - Floating point arithmetic, positive and negative numbers…... Assuming they are binary floating point numbers, you can’t. It is possible to make an algorithm, by a fairly easy and obvious method *, to see whether two binary floating point numbers are the same to two decimal points quite a lot of the time.
15. Floating Point Arithmetic Issues and Limitations
0.1 and 0.7 are also non-terminating in binary, so they are also truncated, and the sum of these truncated numbers does not add up to the truncated binary representation of 0.8 (which is why (floor)(0.8*10) yields a different, more intuitive, result). However, since 2 is a factor of 10, any number that terminates in binary also terminates in decimal.... The information you need is all in the Wikipedia pages on floating point arithmetic and IEEE 754. I agree with the comment suggesting that you may do better on a computer stackexchange site, but let me sketch a few hints about the mathematics that may help you understand the Wikipedia pages.
14. Floating Point Arithmetic Issues and Limitations
Decimal floating points support a feature not available for binary floating points: They can represent the precision of the original number, i.e., they can keep track of trailing zeros after the decimal point (unless the number of digits would exceed the number of decimals for the decimalfloating point). how to delete messages from rogers In other words, when we add or subtract fixed-point numbers, the binary point in the sum (or difference) will be located in exactly the same place as in the two numbers upon which we are operating. When multiplying two 8-bit fixed-point numbers we will need 16 bits to hold the product.
Understanding Fixed Point and Floating Point Number
While a floating-point representation can't represent all numbers precisely, it does give us a guaranteed number of significant digits. For this 8-bit representation, we get a single digit of precision, which is pretty limited. To get more precision, we need more mantissa bits. Suppose we defined a similar 16-bit representation with 1 bit for the sign bit, 6 bits for the exponent plus 31, and how to add a keyboard on mate 10 Convert to binary - convert the two numbers into binary then join them together with a binary point. Work out the exponent - This is done by working out how many spaces the binary point needs to be moved so that it is just after the first 1 in the result.

How To Add Two Binary Floating Point Numbers
It explains the binary representation of these numbers, how to convert to decimal from floating point, how to convert from floating point to decimal, discusses special cases in floating point, and finally ends with some C code to further one's understanding of floating point. This document does not cover operations with floating point numbers.

- i'm trying to understand how to add two numbers in IEE754 half precision format , i haven't found a good reference/tutorial on this , so i've tried to follow the 32 bit floating point addition procedure , but at some point i'm stucked , what i know is:
- Convert to binary - convert the two numbers into binary then join them together with a binary point. Work out the exponent - This is done by working out how many spaces the binary point needs to be moved so that it is just after the first 1 in the result.
- In this program, user is asked to enter two numbers (floating point numbers). Then, the product of those two numbers is stored in a variable and displayed on the screen. Then, the product of those two numbers is stored in a variable and displayed on the screen.
