The right way to compare a System.Double to '0' (a number, int?)

Question

Sorry, this might be a easy stupid question, but I need to know to be sure.

I have this if expression,

void Foo()
{
    System.Double so         


        

Answer 1

I dont' think it's equal, honestly. Consider yuor own example: something = 0.9, or 0.0004. In first case it will be FALSE, in second case it will be TRUE. Dealing with this types I usually define for me precision percentage and compare within that precision. Depends on your needs. something like...

if(((int)(something*100)) == 0) {


//do something
}

Hope this helps.
