Description of the problem
In the Basis Library, the type IEEEReal.decimal_approx has a field
class.https://smlfamily.github.io/Basis/ieee-float.html#SIG:IEEE_REAL.decimal_approx:TY
but in SML/NJ the field is called
kindinstead ofclass:type decimal_approx =
{digits:int list, exp:int, kind:IEEEReal.float_class, sign:bool}
Consequently code using this field is not portable.
