WebThe maximum bit-field length is 64 bits. To increase portability, do not use bit fields greater than 32 bits in size. The following structure has three bit-field members … WebFor example, a one-bit Number field can store only integers ranging from 0 to 255. The Field Size property also determines how much disk space each Number field value requires. Depending on the field size, the number can use exactly 1, 2, 4, 8, 12, or 16 bytes. Note: Text and Memo fields have variable field value sizes.
