Is type byte an 8-bit unsigned integer like the standard exact width type uint8_t?

| May 18, 2015 at 22:56 | comment | added | Matt Borja | Ah, but I'm not quite ready for assembly just yet :) Will add a note to myself to look into it though... | |

Clarify platform requirements.

| May 18, 2015 at 22:55 | comment | added | Reinderien | If you care about cost and you're on a microcontroller, your overflow logic should be implemented in assembly and check the carry flag. | |
| May 18, 2015 at 22:54 | comment | added | Matt Borja | Ah, I guess I should've this pointed out: This is for an Atmega328 (i.e. Arduino Uno) and I'm told that merely adding 1 to a uint64 can be a bit costly: forum.arduino.cc/index.php?topic=58697.msg422187#msg422187 | |
| May 18, 2015 at 22:50 | comment | added | Reinderien | If it's 8 or 16 bytes, you shouldn't be stringing together bytes - string together uint64s. The overflow logic will operate much more quickly. | |
