How many bits is a double in c++
Microsoft-specific: The representation of long double and double is identical. However, long double and double are treated as distinct types by the compiler. The Microsoft C++ compiler uses the 4- and 8-byte IEEE-754 floating-point representations.

Double:It is 64-bit double-precision floating point type. It has 14 – 15 digit Precision. To initialize a double variable, use the suffix d or D. But it is not mandatory to use suffix because by default floating data types are the double type.
