* Move qrand to libc64 * use an union to avoid type punning * __osMalloc * math64.c * fixed_point.h * sleep * aprintf.h * sprintf * malloc * use original names on aprintf.c and malloc.c * qrand cleanup pass * use original names of sleep.c * og names for sprintf * more cleanup * format * fixes * whoops * use ARRAY_COUNT again * comment * Use `fu` * forgot this one * review * fix * sneak a tiny cleanup
