## digitalmars.D.learn - Unary operators for Variants

- Jeff (9/9) Mar 09 So, I can't seem to get unary operators to work with variants.
- Imperatorn (3/12) Mar 10 Try jsvar

So, I can't seem to get unary operators to work with variants. For example: Variant x = 10; writeln(-x); // Error: x is not of arithmetic type, it is a VariantN!32LU Obviously binary operators like + work fine. Is there a reason opUnary wasn't implemented as well? Is there a work-around for me to implement it myself outside of the VariantN class? Thanks!
