This is my code for getting the body mass index (BMI) of a person it's okay when running but my only problem is how do i turn the answer in 2 decimals? for example:
Your height in meters: 1.70 Your weight in kilograms: 50 Your BMI result:17.301032(UNDER-WEIGHT)
i want the output to be only 17.30 or in 2 decimals. what should i change?
