greater_or_equal_than?

[greyblake]

I paste this message from reddit here, I don't lose/forget about it:

Nice!
One thing that I would miss would be something like
#[nutype(validate(greater_or_equal_than=0.0))]
instead of min=0 as I find this notation more natural. So basically all the greater / greater_or_equal, lesser/ lesser_or_equal etc.
For example, if you want a float that is strictly more that zero (because you might want to divide by it), then min=0 doesnt work as it accepts zero. I see that you can use with = but a named case for those usual cases would be more expressive imo. What do you think?

alternatives:

>= ge min
<= le max
< lt less lower under below
> gt more/greater higher over above
== eq equals is
!= ne not

personally i suggest adding a pair like less/greater or below/above. ideally the macro should reject those with both a min and a greater or a max and a less, or (an equals or not) and something else.

Decided to use

• less
• less_or_equal
• greater
• greater_or_equal
