1 Formula Result Notes How it works
2 =DECIMAL(“FF”,16) 255 Converts the hexadecimal (base 16) value FF to its equivalent decimal (base 10) value “F” is in position 15 in the base 16 number system. Because all number systems start with 0, the 16th character in hexadecimal will be in the 15th position
3 =DECIMAL(111,2) 7 Converts the binary (base 2) value 111 to its equivalent decimal (base 10) value “1” is in position 1 in the base 2 number system
4 =DECIMAL(“1100”,2) 12 Converts the binary (base 2) value 1100 to its equivalent decimal (base 10) value
5 =DECIMAL(“70122”,8) 28754 Converts the binary (base 8) value 70122 to its equivalent decimal (base 10) value
