 Computes the [variance][variance] of a double-precision floating-point strided array ignoring `NaN` values and using a one-pass trial mean algorithm and alternative indexing semantics.
 
 ```c
-const double x[] = { 1.0, -2.0, NaN, 2.0 };
+const double x[] = { 1.0, -2.0, 0.0/0.0, 2.0 };
 
 double v = stdlib_strided_dnanvariancech_ndarray( 4, 1.0, x, 1, 0 );
