Bit fields not allowed for type c_float
WebYou can enter the number into a float field in a file or personal geodatabase, but it will be rounded to 123,457, a number containing the permissible 6 digits. If you need to store this number precisely, you could store it in a double field. In C, we can specify the size (in bits) of the structure and union members. The idea of bit-field is to use memory efficiently when we know that the value of a field or group of … See more
