2. 64-bit computing - Wikipedia

   en.wikipedia.org/wiki/64-bit_computing

   A 64-bit word can be expressed as a sequence of 16 hexadecimal digits. In computer architecture, 64-bit integers, memory addresses, or other data units [a] are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of ...

7. Double-precision floating-point format - Wikipedia

   en.wikipedia.org/wiki/Double-precision_floating...

   Double-precision binary floating-point is a commonly used format on PCs, due to its wider range over single-precision floating point, in spite of its performance and bandwidth cost. It is commonly known simply as double. The IEEE 754 standard specifies a binary64 as having: Sign bit: 1 bit. Exponent: 11 bits.
