template <numeric T1>
KFR_FUNCTION flt_type<T1> sinc(const T1& x)

Returns the (normalized) sinc function of x.

\\[ sinc(x) = \begin{cases} \frac{\sin(x)}{x} & |x| > \varepsilon \\ 1 & |x| \le \varepsilon \end{cases} \\]

Template parameters
T1	Scalar or vector type. Integer arguments are promoted to a floating-point type.

Parameters
x	Argument in radians.

Returns
	Sinc of `x,` in the same floating-point type as `x` (or its element type for vectors).
