Double are a special data type of floating point. It's generally a short name for the “double-precision 64-bit format defined in IEEE 754”.

Modern systems usually provide floating-point support that conforms to double.

Double type of the language C is usually implemented as a 64-bit IEEE 754 number, which uses 52 bits of space for the mantissa.
