How do computers and programmers use octal
WebOctal and hex are the popular ones. Most all computers stores their information in memory using octal or hex representation using binary. All computers use binary as the base as it represents the electrical on/off designation. Zero and one. I have never worked with a computer where the memory dumps were in decimal. WebThe simplest reason is that, the computer does not see this, it only sees the binary. This really just aids the programer. Binary is a mess to look at, octal does not usually work since an octal number is three bits and historically computers have been using 16,32,64 bit instruction sets, none of which are divisible by 3, leaving hex as the best choice.

No idea why anyone would use octal. E.g. when extracting the Green value from an RGB int, you would use (rgb >> 8) & 0xFF because 0xFF is much better than 255, 0377, and 0b11111111 in this context. You'd use octal in 18-bit computing, obvs.
WebFor the same reason, with today computers we use the hexadecimal system. The C programming language makes it easy to use the octal system.
