rational-valued?[procedure] real-valued? obj
[procedure] rational-valued? obj
[procedure] integer-valued? obj
R6RS: Like real?, rational?, and integer?, respectively,
but these allow obj to be non-number objects.
These also differ from real? etc. when obj is a complex number
with inexact zero imaginary part. From R6RS:
(real? -2.5+0.0i) => #f
(real-valued? -2.5+0.0i) => #t
See also real?, rational?, integer?.
