+# InputNumber Component — Design Spec
+
+**Date:** 2026-04-16  
+**Branch:** `form.inputnumber` (to be created)  
+**Reference:** [Vue InputNumber](https://github.com/cdek-it/vue-ui-kit/tree/form.InputNumber/src/plugins/prime/stories/Form/InputNumber)
+
+---
+
+## Overview
+
+Angular wrapper component for PrimeNG `InputNumber`, following the same patterns as `InputTextComponent`. Provides a styled numeric input with optional increment/decrement buttons, currency formatting, and min/max/step constraints. Integrates with Angular Forms via `ControlValueAccessor`.

+
+## Component API (`InputNumberComponent`)
+
+**Selector:** `input-number`  
+**Standalone:** yes  
+**CVA value type:** `number | null`
+
+### Inputs
+
+| Prop | Type | Default | Description |
+|---|---|---|---|
+| `size` | `'small' \| 'base' \| 'large' \| 'xlarge'` | `'base'` | Размер поля |
+| `placeholder` | `string` | `''` | Подсказка при пустом поле |
+| `disabled` | `boolean` | `false` | Отключает взаимодействие |
+| `readonly` | `boolean` | `false` | Только для чтения |
+| `invalid` | `boolean` | `false` | Невалидное состояние |
+| `showButtons` | `boolean` | `true` | Показывать кнопки +/− |
+| `buttonLayout` | `'horizontal' \| 'vertical' \| 'stacked'` | `'horizontal'` | Расположение кнопок |
+| `mode` | `'decimal' \| 'currency'` | `'decimal'` | Режим отображения |
+| `currency` | `string` | `'RUB'` | Код валюты (ISO 4217) при `mode="currency"` |
+| `locale` | `string` | `'ru-RU'` | Локаль форматирования |
+| `prefix` | `string \| undefined` | `undefined` | Префикс перед значением |
+| `suffix` | `string \| undefined` | `undefined` | Суффикс после значения |
+| `min` | `number \| undefined` | `undefined` | Минимальное значение |
+| `max` | `number \| undefined` | `undefined` | Максимальное значение |
+| `step` | `number` | `1` | Шаг изменения |
+| `minFractionDigits` | `number` | `0` | Мин. знаков после запятой |
+| `maxFractionDigits` | `number` | `20` | Макс. знаков после запятой |
+| `fluid` | `boolean` | `false` | Растягивает на всю ширину |
+
+### Size mapping
+
+| `size` | `pSize` (PrimeNG) | CSS class |
+|---|---|---|
+| `'small'` | `'small'` | — |
+| `'base'` | `undefined` | — |
+| `'large'` | `'large'` | — |
+| `'xlarge'` | `'large'` | `p-inputnumber-xlg` (on host) |
+
+The `p-inputnumber-xlg` class is applied via `[ngClass]` on the `p-inputnumber` element so CSS cascade can target `.p-inputnumber-xlg .p-inputnumber-input`.
+
+### Icons
+
+Increment button: `<i class="ti ti-plus"></i>` via `#incrementicon` ng-template.  
+Decrement button: `<i class="ti ti-minus"></i>` via `#decrementicon` ng-template.
+
+### CVA
+
+- `writeValue(v: number | null)` — stores to `modelValue`
+- `registerOnChange` / `registerOnTouched` — standard
+- `setDisabledState` — sets `disabled`
+- `onValueChange(v: number | null)` — called on PrimeNG `(onInput)` event, calls `_onChange`
+
+---
+
+## CSS Overrides (`src/prime-preset/tokens/components/inputnumber.ts`)
+
+```typescript
+export const inputnumberCss = ({ dt }) => `
+  .p-inputnumber-button {
+    border-width: ${dt('inputnumber.extend.borderWidth')};
+  }
+
+  .p-inputnumber-horizontal .p-inputnumber-button {
+    min-height: ${dt('inputnumber.extend.extButton.height')};
+  }
+
+  .p-inputnumber-horizontal:has(.p-inputnumber-input:disabled) .p-inputnumber-button {
+    background: ${dt('inputtext.root.disabledBackground')};
+    color: ${dt('inputtext.root.disabledColor')};
+  }
+
+  .p-inputnumber.p-inputnumber-xlg .p-inputnumber-input {
+    font-size: ${dt('inputtext.extend.extXlg.fontSize')};
+    padding: ${dt('inputtext.extend.extXlg.paddingY')} ${dt('inputtext.extend.extXlg.paddingX')};
+  }
+`;
+```
+
+---
+
+## map-tokens.ts
+
+Add import and entry:
+
+```typescript
+import { inputnumberCss } from './tokens/components/inputnumber';
+
+// in components:
+inputnumber: {
+  ...(tokens.components.inputnumber as unknown as ComponentsDesignTokens['inputnumber']),
+  css: inputnumberCss,
+},
+```
+
+---
+
+## Stories
+
+### `inputnumber.stories.ts`
+
+- `meta`: `title: 'Components/Form/InputNumber'`, `component: InputNumberComponent`, `tags: ['autodocs']`
+- `argTypes`: all props from API table above
+- `args`: defaults from API table
+- `Default` story: dynamic template built from args (same pattern as InputText Default)
+- Re-exports: `FloatLabel`, `Currency`, `MinMax`
+
+### `examples/inputnumber-float-label.component.ts`
+
+Uses native `p-inputnumber` (not the wrapper) as direct child of `p-floatlabel variant="in"`, because PrimeNG FloatLabel CSS relies on sibling selectors that don't work through wrapper components. Shows `showButtons`, `buttonLayout="horizontal"`, Tabler icon templates. `controls: { disable: true }`.
+
+### `examples/inputnumber-currency.component.ts`
+
+Pure `StoryObj` (no `@Component`), `render: (args) => ({ props: { ...args, value: null }, template })`. Args preset: `mode: 'currency'`, `currency: 'RUB'`, `locale: 'ru-RU'`. All other props bound through Controls.
+
+### `examples/inputnumber-minmax.component.ts`
+
+Pure `StoryObj`. Args preset: `min: 0`, `max: 100`, `step: 1`. Shows constraint behaviour.
+
+---
+
+## Constraints
+
+- No `styles: [...]` in Angular `@Component` decorator — use `const styles = ''` (webpack base64 path bug)
+- Storybook story layout: Tailwind classes only, no inline `style="..."`
+- Float label: always use native `p-inputnumber` directly — never the wrapper component — inside `p-floatlabel`
+- Default story must build template dynamically from args so the code snippet updates with Controls
+- `source.code` in float-label example should not include the outer `<div class="pt-6">` wrapper
