The '''patent val''' (a.k.a. '''nearest edomapping~~''', '''integer uniform map''', and '''simple map~~''') for an [[edo]] is a list of numbers you obtain by finding the closest rounded approximation to each [[prime harmonic]] in the tuning, assuming [[2/1|octaves]] are pure (or in other words, assuming the edo number is an integer). The basic application of a patent val is that you round prime harmonics to edosteps, and then deduce the number of steps of an arbitrary just interval based on its [[prime factorization]].

For example, the patent val for 17edo is {{val| 17 27 39 }}, indicating that the closest mapping for 2/1 is 17 steps, the closest mapping for 3/1 is 27 steps, and the closest mapping for 5/1 is 39 steps. This means, if octaves are pure, that 3/2 is 706 cents, which is what you get if you round off 3/2 to the closest location in 17-equal, and that 5/4 is 353 cents, which is what you get is you round off 5/4 to the closest location in 17-equal.
