What words can you spell with hexadecimal?
Theory. Hex letters can be used to write english words, like cafebabe, or deadbeef. This is handy for developers, because we can put “recognizable text” in binary data. Unfortunately, there aren’t that many words spelled with just the letters a through f.
How do you write hexadecimal notation?
A single hexadecimal digit can be represented by 4 binary digits (Refer Table 1). Java and C uses 0x or 0X to represent hexadecimal numbers. Characters (‘A’ to ‘F’) in a hexadecimal number can be written either in upper case or lower case. For example, 0xa8b3d is same as 0xA8B3D.
What does 0x4000 mean?
In C and languages based on the C syntax, the prefix 0x means hexadecimal (base 16). Thus, 0x400 = 4×(162) + 0×(161) + 0×(160) = 4×((24)2) = 22 × 28 = 210 = 1024, or one binary K. And so 0x6400 = 0x4000 + 0x2400 = 0x19×0x400 = 25K.
