Answer. The decimal equivalent of (101010.1) is 42.5
Group of 4 bits can also be represented as hexadecimal numbers. Refer Table below.
Decimal to binary conversion conversions:
Formula to convert a decimal number to binary: Is derived using an example below.
Example: To represent 17.25 in digital system we will need to use 5 bits.
Step1: - 17/2 = 8 + ½
a0 = LSB = 1
Step2: - 8/2 = 4 + 0
a1 = left bit to LSB (a0) = 0
Binary Numbers Discussion
Bit: The smallest unit of a digital system is called a ‘bit’. A bit can take one
of the two logical values of 1 or 0. A set of 4 bits can represent (=2^4) 16 decimal
values. And a set of 5 bits can represent (=2^5) 32 decimal values... and so on.
