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.


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.
