13 = D in hex. If you're using two digits to represent the hex number - its 0D
In hex, that would be 1C8
The space character in ASCII is CHR(32), so in HEX, that would be 0x20
hex =7
Binary(1010) = Hex(A)
(1F)hex = (31)decimal
The decimal number 111 is written in hexadecimal as 6F.
(10)hex = (16)decimal
The hex code #FF0000 is pure red. Hexadecimal colors are given in Red, Green, Blue as a number in the hexadecimal number system. The number FF, in hex, is the same as the number 255 in decimal. Pure blue? #0000FF Pure green? #00FF00 And any of the 16 million or so other colors hex is capable of.
16 is the 4th power of 2. So a hexadecimal number is converted to binary by replacing each hex digit by the 4-bit binary number having the same value. Conversely, in converting binary to hexadecimal, we group every 4 bits starting at the decimal (binary?) point and replace it with the equivalent hex digit. For example, the hexadecimal number 3F9 in binary is 1111111001, because 3 in binary is 11, F (decimal 15) is 1111, and 9 is 1001.
Convert each group of 4 bits into one hexadecimal digit. 1010 is "A" in hexadecimal, so this particular number is "AA".
Since the letter O cannot be part of a hexadecimal number it has to be assumed that the question is about "AE"&"O", and converting from hex to decimal, this is 174O.
