How this conversion works
One hundred in binary needs seven bits. It is a handy reminder that decimal round numbers are nothing special to a computer — 100 has no tidy binary form.
Each base just uses a different set of digits for the same quantity. Reading
100 as a decimal number gives the decimal value
100; expressing that same value in base two, eight or sixteen
produces the rows above. To convert any number between bases — including custom bases from 2
to 36 — use the number base converter.
