Binary to decimal

(a8 a7 a6 a5 a4 a3 a2 a1 a0)2 = a8*28+a7*27+a6*26+a5*25+a4*24+a3*23+a2*22+a1*21+a0*20

Convert (101,1)2 to base 10:

(101,1)2 = 1*22+0*21+1*20+1*21 = 4+0+1+0,5 = (5,5)10

Decimal to binary

Convert (357)10 to binary:

357/2 178/2 89/2 44/2 22/2 11/2 5/2 2/2 1/2 0
10 1 0 0 1 1 0 1
← ← ← ← ← ← ← ←

(257)10 = (101100101)2

Hexadecimal to binary

Convert (1a36d)16 to binary:
(1)16 = (0001)2
(a)16 = (1010)2
(3)16 = (0011)2
(6)16 = (0110)2
(d)16 = (1101)2

(1a36d)16 = (~~000~~11010001101101101)2

Convert (5f6c,ab8)16 to binary:
(5)16 = (0101)2
(f)16 = (1111)2
(6)16 = (0110)2
(c)16 = (1100)2
(a)16 = (1010)2
(b)16 = (1011)2
(8)16 = (1000)2

(5f6c,ab8)16 = (0101111101101100,101010111000)2

Binary to hexadecimal

Convert (0010010111010001,11101100)2 to hexadecimal:

0010 0101 1101 0001 , 1110 1100
2 5 d 1 , 3 c

(10010111010001,111011)2 = (25d1,ec)16
