-| Returns the result of converting the double-precision floating-point value

-| performed according to the IEC/IEEE Standard for Binary Floating-Point
-| Arithmetic---which means in particular that the conversion is rounded
-| according to the current rounding mode.  If `a' is a NaN, the largest
-| positive integer is returned.  If the conversion overflows, the
-| largest unsigned integer is returned.  If 'a' is negative, the value is
-| rounded and zero is returned; negative values that do not round to zero
