Binary to Decimal converter
How to convert from binary to decimal?
Assume we have a n-digits binary number:
dn-1 ... d3 d2 d1 d0
The decimal number is calculated as the sum of the binary digits (dn) multiplies their power of 2 (2n):
decimal number = d0×20 + d1×21 + d2×22 + ...
Example:
Calculate the decimal number of 11010:
110102 = 1â‹…24+1â‹…23+0â‹…22+1â‹…21+0â‹…20 = 2610
