Will the differences below matter significantly in C#?
int a, b;
double result;
result = (double)a / b;
result = a / (double)b;
result = (double)a / (double)b;
Which one do you use?
The cast will occur before the division.
In your examples, it doesn’t matter which one you do as if one operand is a double, the runtime will cast/convert the other to a double as well.
This looks like a micro-optimization – not something worth worrying about or dealing with unless measurements show it is indeed a bottleneck.
