Curly parenthesis in calc graph

why following statement is equal 1 ? I was expecting 0 is not less than 0, thus should be 0. where is my understanding fails ?

I want that if the result is < 0 get 1, otherwise 0.

Thanks

It’s reading the right side of the inequality as 01 (the space isn’t doing anything). So it is true.

Thanks, I’ve change it and it works.
