Keyboard Slider Float Tweaks Not Working With Small Range And %.0f Format

[DomGries]

Expected:
Slider should change value when activating slider keyboard input and using arrow keys

Current:
Slider does not change value when activating slider keyboard input and using arrow keys with small range and format being "%.0f"

Reproduce:

float fieldOfView;
ImGui::SliderFloat("fov", &fieldOfView, 80.f, 120.f, "%.0f");

Details:
There is code in ImGui::SliderBehaviorT like delta /= 100.0f; // Gamepad/keyboard tweak speeds in % of slider bounds which results in step size smaller than 1 with small range and format being "%.0f"

My workaround has been to use ImGui::SliderInt and casting the values between float and int

Note that holding the arrow keys would work, the float is being modified but there's not enough precision to see it. Near that code I think we should change in SliderBehaviorT:

if (is_decimal || is_power)

With

const int decimal_precision = is_decimal ? ImParseFormatPrecision(format, 3) : 0;
if ((decimal_precision > 0) || is_power)

To match the old behavior. I'll have to think what other side effect it may have.

Fixed.
