Question

I have a decimal variable that I would like to negate if a boolean variable is true. Can anyone think of a more elegant way to do it than this:

decimal amount = 500m;
bool negate = true;

amount *= (negate ? -1 : 1);

I’m thinking something along the lines of bitwise operators or a strictly mathematical implementation.

Answer 1

Personally, I would just use an if statement, since I feel that it’s the most clear in terms of intent:

decimal amount = 500m;
bool negate = true;

// ...

if (negate)
    amount *= -1;

This is really not any extra typing (it’s actually shorter!), and more clear in my opinion.
