Convert the binary number into a hexadecimal number.

A binary number is converted to hexadecimal number by making a group of 4 bits from the binary number given. Start making the group from Least Significant Bit (LSB) and start making group of 4 to Most Significant (MSB) or move in outward direction. If the there are less than 4 bits in last group then add corresponding zeroes to the front and find the corresponding hexadecimal number according to the 4 bits. For example:-

for this binary number 100111001011011.

100 1110 0101 1011

There is one bits less in the last group so add 1 zero (0) to it.

0100 1110 0101 1011

4 E 5 B

100111001011011 = 4E5B

101011.1010

0010 1011. 1010
