Text in "InputInt" is not centered.

[gilpazintel]

Version/Branch of Dear ImGui:

Version 1.90.9

Back-ends:

imgui_impl_XXX.cpp + imgui_impl_XXX.cpp

Compiler, OS:

Windows 11

Full config/build information:

No response

Details:

this issue is as a follow-up of issue: https://github.com/ocornut/imgui/issues/7344
as commented in the above issue, the center of the text is not implemented yet.
I want to make the text center and use a minimum extra code as possible.
could you please advise if the below is the best way to do it?

note: although modifying the ImGui source at me side would be cleaner, I want to avoid it so further update of ImGui will be easy to merge.

thank you

Minimal, Complete and Verifiable Example code:

const char* format = "%d";
int step_fast = 100;

char buf[64];
ImGui::DataTypeFormatString(buf, IM_ARRAYSIZE(buf), data_type, v, format);

ImGuiInputTextFlags flags = ImGuiInputTextFlags_AutoSelectAll | (ImGuiInputTextFlags)ImGuiInputTextFlags_NoMarkEdited; // We call MarkItemEdited() ourselves by comparing the actual data rather than the string.
flags |= (ImGuiInputTextFlags)ImGuiInputTextFlags_LocalizeDecimalPoint;

bool value_changed = false;
bool pushed_style_var = false;


const float button_size = ImGui::GetFrameHeight();

ImGui::BeginGroup(); // The only purpose of the group here is to allow the caller to query item data e.g. IsItemActive()
ImGui::PushID(label);
ImGui::SetNextItemWidth(ImMax(1.0f, ImGui::CalcItemWidth() - (button_size + style.ItemInnerSpacing.x) * 2));

pushed_style_var = handleTextCentering(buf, style);

    value_changed = ImGui::DataTypeApplyFromText(buf, data_type, v, format, (flags & ImGuiInputTextFlags_ParseEmptyRefVal) ? p_data_default : NULL);

if (pushed_style_var)
