Calculate Device Energy Efficiency | Dataford Interview Questions

Write a function to calculate the energy efficiency of a device based on given parameters.

Define efficiency as (useful_energy / input_energy) * 100. Return the result as a floating-point percentage.

Use the signature calculate_efficiency(input_energy, useful_energy). Both parameters are numeric, input energy is positive, and useful energy is nonnegative.

Constraints

input_energy is a positive integer or floating-point number
useful_energy is a nonnegative integer or floating-point number
useful_energy <= input_energy
Return the efficiency as a floating-point percentage

Function Signature

def calculate_efficiency(input_energy, useful_energy):
