Decimal Weights128 32 16 4 1 = 18110

Add the decimal weights of the “1” bits

Decimal to Binary1. Find the largest binary bit that will fit in the number without going over the number

2. Mark that bit as “on” and subtract the bit weight value from the decimal number

3. Repeat steps 1 and 2 until there are no more numbers remaining in the decimal number
