Best Answer

Write each hexadecimal digit straight into binary:

5 = 0101

4 = 0100

2 = 0010

So 0x542 = 0101 0100 0010 = 10101000010 (without the spaces).

Hex digit to binary conversion:

0 = 0000, 1 = 0001, 2 = 0010, 3 = 0011

4 = 0100, 5 = 0101, 6 = 0110, 7 = 0111

8 = 1000, 9 = 1001, a = 1010, b = 1011

c = 1100, d = 1101, e = 1110, f = 1111

What does hexadecimal base 16 convert binary equal?

16 is the 4th power of 2. So a hexadecimal number is converted to binary by replacing each hex digit by the 4-bit binary number having the same value. Conversely, in converting binary to hexadecimal, we group every 4 bits starting at the decimal (binary?) point and replace it with the equivalent hex digit. For example, the hexadecimal number 3F9 in binary is 1111111001, because 3 in binary is 11, F (decimal 15) is 1111, and 9 is 1001.


How do you convert hexadecimal 4c.B7 to Binary?

Convert each hex digit to four binary digits. If you get less than three (for example, 7 --> 111), fill it out with zeroes to the left (in this case, 0111).


The minimum number of bits required to store the hexadecimal number FF is?

To store the hexadecimal number FF, we need to convert it to binary first. FF in hexadecimal is equivalent to 1111 1111 in binary, which requires 8 bits to represent. Each hexadecimal digit corresponds to 4 bits in binary, so two hexadecimal digits (FF) require 8 bits to store.


Why people are using Hexadecimal rather than binary numbers while doing programs?

hexadecimal can express 16 bit binary in 4 place form, not 16.


What is the 4-binary number assoiated with the hexadecimal symbol C?

0xc = 1100 Hexadecimal digits use exactly 4 binary digits (bits). The 0x0 to 0xf of hexadecimal map to 0000 to 1111 of binary. Thinking of the hexadecimal digits as decimal numbers, ie 0x0 to 0x9 are 0 to 9 and 0xa to 0xf are 10 to 15, helps with the conversion to binary: 0xc is 12 decimal which is 8 + 4 → 1100 in [4 bit] binary.

Why is Hexadecimal used?

It is used because it is easier to convert to and from binary to hexadecimal than decimal, and it uses less characters than binary. For instance: decimal: 65535 hex: FFFF binary: 1111111111111111


How do you convert binary to hexadecimal using assembly language?

Well, honey, in assembly language, you convert binary to hexadecimal by grouping the binary digits into sets of four, then converting each group into its hexadecimal equivalent. You can use bitwise operations like shifting and masking to make the conversion process smoother. Just remember, in the end, hexadecimal is just a fancy way of saying "base 16."
