I've tested the -FLT_MAX/2.0 .. FLT_MAX/2.0 ranged slider in Dear ImGui itself and it works fine, so something is amiss here

Interestingly recreating the same basic example in imgui-rs also works completely fine:

use imgui::*;

mod support;

fn main() {
    let mut value: f32 = 0.0;
    let system = support::init(file!());
    system.main_loop(move |run, ui| {
        Slider::new("f32 value with range", -f32::MAX/2.0, f32::MAX/2.0)
            .build(ui, &mut value);
    });
}

Something about how the slider.rs example specifically is going wrong

🤦

I wrote -f32::MIN/2.0 which is "quite similar" to f32::MAX/2.0 so the slider in example is acting completely correctly (as far as can be expected for a slider to and from the same value). I think I meant to write -f32::MAX/2.0, f32::MAX/2.0, and then completely missed the difference been MIN and MAX when comparing to the working example above!

Good news being everything is working as expected!
