Map Numbers to Different Ranges

Introduction

In programming, we often need to map a number from one range to another range. For example, we may have a number that ranges from 0 to 10, but we need to map it to a range of 0 to 100. This can be useful in many applications, such as scaling data or converting units.

Map Number to Range

Write a function called num_to_range that takes five arguments: num, inMin, inMax, outMin, and outMax. The function should return num mapped between outMin-outMax from inMin-inMax. In other words, the function should take a number (num) that falls within a certain range (inMin-inMax) and map it to a new range (outMin-outMax).

def num_to_range(num, inMin, inMax, outMin, outMax):
  return outMin + (float(num - inMin) / float(inMax - inMin) * (outMax
                  - outMin))

num_to_range(5, 0, 10, 0, 100) ## 50.0

Summary

In this challenge, you were asked to write a function that maps a number from one range to another range. This can be a useful tool in many programming applications.
