How to ask Mathematica to give NumberLinePlot of $sin x$ for non-integer $x$?

Question

How to ask Mathematica to give NumberLinePlot of $sin x$ on domain $xin(0,30)notinmathbb{N}$. I need solution for non-integer $x$
NumberLinePlot[{Sin[x] < 0, Sin[x] >= 0}, {x, 0, 30}]

You could include an additional predicate:
NumberLinePlot[
    {
    Sin[x] < 0 && Mod[x, 1] != 0, 
    Sin[x] >= 0 && Mod[x, 1] != 0
    },
    {x, 0, 30}
]

positiveSol = 
 x /. Solve[
   Sin[x] > 0 && 0 < x < 30 && x ∈ PositiveIntegers]
negativeSol = 
 x /. Solve[
   Sin[x] < 0 && 0 < x < 30 && x ∈ PositiveIntegers]
NumberLinePlot[! AnyTrue[positiveSol, EqualTo[x]], {x, 0, 30}]
NumberLinePlot[! AnyTrue[negativeSol, EqualTo[x]], {x, 0, 30}]
