問題
Body mass index (BMI) is weight in kilograms divided by the square of height in meters.
Implement body_mass_index(weight_kg, height_m).
Input
weight_kg: Weight in kilograms. height_m: Height in meters.
Output
Return weight_kg / (height_m × height_m).
制約
1 ≤ weight_kg ≤ 500; 0.5 ≤ height_m ≤ 2.5
例
例 1
入力:
height_m = 1.8
weight_kg = 72.0
期待される出力:
expected = 22.222222
入力:
double height_m = 1.8;
double weight_kg = 72.0;
期待される出力:
double expected = 22.222222;
入力:
double height_m = 1.8;
double weight_kg = 72.0;
期待される出力:
double expected = 22.222222;
解説
1.8 × 1.8 = 3.24 and 72 / 3.24 ≈ 22.2222.
例 2
入力:
height_m = 1.0
weight_kg = 50.0
期待される出力:
expected = 50.0
入力:
double height_m = 1.0;
double weight_kg = 50.0;
期待される出力:
double expected = 50.0;
入力:
double height_m = 1.0;
double weight_kg = 50.0;
期待される出力:
double expected = 50.0;
解説
With a height of 1 meter the BMI equals the weight: 50.
