1.0 a positive to hiv test?

Probably not: There are at least 20 different HIV blood tests in use around the world, with different cut-off values for positive results. For most or all, 1.0 is negative. Since you know the specific number, you must have a written report; it should provide that information for your test. If it does not, or if you don't understand it, contact the doctor, clinic or laboratory where the test was done.
