description

`Real-valued?`, `rational-valued?`, and `integer-valued?` test whether a given number object can be coerced to the specified type without loss of numerical accuracy.  They are equivalent to the versions of `real?`, `rational?`, and `integer?` that existed in R5RS.

Specifically, the behavior of these predicates differs from the behavior of `real?`, `rational?`, and `integer?` on complex number objects whose imaginary part is inexact zero.

These procedures provide R6RS base compatibility as well.

The WG voted to reject the additional procedures and to roll back the regular procedures to the R5RS definitions.
