What is the binary code for 64111?

Answer 1

I assume you mean decimal 64,111

You could assemble a table of powers of 2, then use successive subtraction to convert to the binary expansion.

I cheated and used the built-in programming calculator on my PC.

It says that 64111 (decimal) = FA6F (hexadecimal)

This can easily be expanded to binary digit by digit:

F=1111

A=1010

6=0110

F=1111

So the final answer is:

1111101001101111

Note that the number 2^16 = 65,536 (which is slightly bigger) has a binary equivalent of

10000000000000000

i.e., a one followed by 16 zeroes.
