An implementation of a floating-pointsystem conforming to this standard may be realized entirely in software, entirely in hardware, or in any combination of software and hardware.
此规范中的浮点数系统可以通过软件、硬件,或者软硬件相结合的形式来实现。

On a 64-bit system, integral types are converted to 64-bit integral types, and single precision floatingpoint types are promoted to double precision.
在 64 位系统上,整型被转换成 64 位的整型值,单精度的浮点类型被转换成双精度的浮点类型。

But on a register-based system, the hexadecimal value is read from an integer register, not the floatingpoint register.
