Calculate BMI

Description

Write function bmi that calculates body mass index (bmi = weight / height²).

if bmi <= 18.5 return "Underweight"

if bmi <= 25.0 return "Normal"

if bmi <= 30.0 return "Overweight"

if bmi > 30 return "Obese"

My Solution

def bmi(weight, height)
  case weight/height**2
  when 0..18.5
    'Underweight'
  when 18.6..25.0
    'Normal'
  when 25.0..30.0
    'Overweight'
  else
    'Obese'
  end
end
