-| precision floating-point number.

-|     The input significand `zSig' has its binary point between bits 30

-| significand must be normalized or smaller.  If `zSig' is not normalized,

-| `zExp' must be 0; in that case, the result returned is a subnormal number,

-| and it must not require rounding.  In the usual case that `zSig' is

-| normalized, `zExp' must be 1 less than the ``true'' floating-point exponent.

-| The handling of underflow and overflow follows the IEC/IEEE Standard for

-| Binary Floating-Point Arithmetic.
