random_float
Generate custom floating-point numbers within a specified range using this tool. Set lower and upper bounds to create precise random values for simulations, testing, or data modeling.
Instructions
Generate a random float between low and high.
Args: low: Lower bound (default 0.0) high: Upper bound (default 1.0)
Returns: Random float between low and high
