Float Generator

Generates random floating-point (decimal) numbers within a specified range.

Basic Usage

{
  "price": {"gen": "float"}
}

Without options, generates any float value.

Options

Option	Type	Default	Description
min	number	Integer.MIN_VALUE	Minimum value (inclusive)
max	number	Integer.MAX_VALUE	Maximum value (inclusive)
decimals	integer	2	Number of decimal places (max: 10)

Examples

Price

{
  "price": {"gen": "float", "min": 9.99, "max": 999.99, "decimals": 2}
}

Output: Random float between 9.99 and 999.99 with 2 decimal places (e.g., 49.99)

Percentage

{
  "percentage": {"gen": "float", "min": 0, "max": 100, "decimals": 1}
}

Output: Random float between 0.0 and 100.0 with 1 decimal place (e.g., 73.5)

Temperature

{
  "temperature": {"gen": "float", "min": -20.0, "max": 40.0, "decimals": 1}
}

Rating

{
  "rating": {"gen": "float", "min": 1.0, "max": 5.0, "decimals": 1}
}

Output: Random rating like 4.2, 3.7, etc.

High Precision

{
  "coordinate": {"gen": "float", "min": -180, "max": 180, "decimals": 6}
}

Output: Precise coordinates like 123.456789

Common Patterns

Product Pricing

{
  "products": {
    "count": 100,
    "item": {
      "id": {"gen": "uuid"},
      "name": {"gen": "lorem.word"},
      "price": {"gen": "float", "min": 9.99, "max": 999.99, "decimals": 2},
      "discount": {"gen": "float", "min": 0, "max": 50, "decimals": 0}
    }
  }
}

Financial Data

{
  "transactions": {
    "count": 500,
    "item": {
      "id": {"gen": "uuid"},
      "amount": {"gen": "float", "min": 10.00, "max": 10000.00, "decimals": 2},
      "fee": {"gen": "float", "min": 0.50, "max": 50.00, "decimals": 2},
      "taxRate": {"gen": "float", "min": 0.05, "max": 0.15, "decimals": 3}
    }
  }
}

Measurements

{
  "measurements": {
    "count": 1000,
    "item": {
      "id": {"gen": "uuid"},
      "weight": {"gen": "float", "min": 0.1, "max": 100.0, "decimals": 2},
      "height": {"gen": "float", "min": 0.5, "max": 2.5, "decimals": 2},
      "temperature": {"gen": "float", "min": 15.0, "max": 30.0, "decimals": 1}
    }
  }
}

Ratings and Scores

{
  "reviews": {
    "count": 200,
    "item": {
      "id": {"gen": "uuid"},
      "rating": {"gen": "float", "min": 1.0, "max": 5.0, "decimals": 1},
      "score": {"gen": "float", "min": 0, "max": 100, "decimals": 1}
    }
  }
}

Geographic Coordinates

{
  "locations": {
    "count": 50,
    "item": {
      "id": {"gen": "uuid"},
      "latitude": {"gen": "float", "min": -90, "max": 90, "decimals": 6},
      "longitude": {"gen": "float", "min": -180, "max": 180, "decimals": 6}
    }
  }
}

Best Practices

1. Always Specify Range: Use min and max for predictable data
2. Appropriate Decimals: Use 2 decimals for currency, 1 for percentages, 6 for coordinates
3. Realistic Ranges: Choose ranges that match real-world scenarios
4. Currency Format: Use 2 decimals for monetary values
5. Max Decimals: Maximum of 10 decimal places supported

Comparison with Number

Generator	Output Type	Use Case
Float	Decimal numbers	Prices, measurements, ratings
Number	Integers	Counts, IDs, quantities
