# Number

> Numeric values with decimal support and numeric constraints.

Use `"type": "number"` for numeric fields that may include decimals.

## Supported numeric keywords

| Keyword                                 | What it does                  |
| --------------------------------------- | ----------------------------- |
| `minimum` / `maximum`                   | Inclusive numeric bounds      |
| `exclusiveMinimum` / `exclusiveMaximum` | Strict numeric bounds         |
| `multipleOf`                            | Restricts values to multiples |

## Example

<CodeGroup>
  ```json JSON Schema theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
  {
    "type": "object",
    "properties": {
      "score": { "type": "number", "minimum": 0, "maximum": 100 },
      "temperature": { "type": "number", "exclusiveMinimum": -273.15 },
      "price": { "type": "number", "minimum": 0, "multipleOf": 0.01 }
    },
    "required": ["score", "temperature", "price"],
    "additionalProperties": false
  }
  ```

  ```python Pydantic theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
  from pydantic import BaseModel, ConfigDict, Field

  class Payload(BaseModel):
      model_config = ConfigDict(extra="forbid")

      score: float = Field(..., ge=0, le=100)
      temperature: float = Field(..., gt=-273.15)
      price: float = Field(..., ge=0, multiple_of=0.01)
  ```

  ```typescript Zod theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
  import { z } from "zod";

  const payloadSchema = z
    .object({
      score: z.number().min(0).max(100),
      temperature: z.number().gt(-273.15),
      price: z.number().min(0).multipleOf(0.01),
    })
    .strict();
  ```
</CodeGroup>

Use `number` for measurements, probabilities, and currency-like values.
