WebC - Unions. A union is a special data type available in C that allows to store different data types in the same memory location. You can define a union with many members, but only one member can contain a value at any given time. Unions provide an efficient way of using the same memory location for multiple-purpose. WebAug 1, 2024 · In this format, a float is 4 bytes, a double is 8, and a long double can be equivalent to a double (8 bytes), 80-bits (often padded to 12 bytes), or 16 bytes. Floating … WebTo store double, computer will allocate 8 byte (64 bit) memory. Where, 1 bit for sign, 11 bit for exponent, 52 bit for significant. only difference between double and float representation is the bias value.
