written as @code{3.0} with an explicit decimal-point is inexact, but
it is also an integer. The functions @code{integer?} and
@code{scm_is_integer} report true for such a number, but the functions
@code{scm_is_signed_integer} and @code{scm_is_unsigned_integer} only
@code{exact-integer?}, @code{scm_is_exact_integer},
@code{scm_is_signed_integer}, and @code{scm_is_unsigned_integer} only

functions like @code{scm_to_signed_integer} only accept exact
integers.
