它們都依據IEEE 754標準，該標準爲32位浮點和64位雙精度浮點二進制小數定義了二進制標準。
These are based on the IEEE 754 standard, which defines a binary standard for 32-bit floating point and 64-bit double precision floating point binary-decimal Numbers.
IEEE 754還定義了正0和負0(在一般的數學中，0是不分正負的，但在計算機數學中，它們可以是正的，也可以是負的)。
IEEE 754 also defines both positive and negative zeros. in regular math, zero is neither positive nor negative.
IEEE 754 represents floating point Numbers as base 2 decimal Numbers in scientific notation.
