### RFIX

coerce to a rational number

    Major Section:  ACL2-BUILT-INS

`Rfix` simply returns any rational number argument unchanged, returning `0` on a non-rational argument. Also see nfix, see ifix, see realfix, and see fix for analogous functions that coerce to a natural number, an integer, a real, and a number, respectively.

`Rfix` has a guard of `t`.

To see the ACL2 definition of this function, see pf.
