I think ten years ago I would also have come up with the idea to compare the results binary

double x = 0.01d;
double y = 0.01d;

x = x * 1.0d

double x = 0.01d;
double y = 0.01d;
bool equal = x == y;  // true
x = x * 1.0d;
equal= x== y;         // true again

var regex = new RegEx(@"D(?:H){0,1}[0-9]{1,2}");

var match = regex.Match(x);

if(match.Success){
   // do something
