Sahuagin 03/25/24 10:55:29 PM #24:	I don't think what you've said about floats and bools is correct. floats are 4 bytes/32 bits. doubles are 8 bytes/64 bits. bools are in many places 4 bytes/32 bits, except in arrays they are 1 byte (each). I don't have a hexdump of memory to confirm this, but some quick tests do seem to confirm it: https://ideone.com/4ELLjh Size of a single Single in bytes is 4. Size of a single Double in bytes is 8. Size of a single Boolean in bytes is 4. An array of type Single of size 5 takes up 20 bytes. An array of type Double of size 5 takes up 40 bytes. An array of type Boolean of size 5 takes up 5 bytes. --- This day is gone. We can't relive it. It's gone forever. <cite>Sahuagin posted [p:979564274] in Writing an...
