WebOct 25, 2024 · 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 fields will never exceed a limit or is within a small range. Bit fields are used when the storage of our program is limited. Need of bit fields in C programming language: WebC标准规定，float类型必须至少能表示6位有效数字，并且取值范围至少是10^-37~10+37。所以，使用float来装365.12345时，前面六位数值是准确的，但是后面的数值略有误差。 uk law ivey test weakness
