JavaScript
const totalRiseCm = 280, steps = 16;
console.log(totalRiseCm / steps); // 17.5 cm per riser
TypeScript
const totalRiseCm = 280, steps = 16;
const riserCm: number = totalRiseCm / steps;
console.log(riserCm); // 17.5
Python
print(280 / 16)  # 17.5 cm per riser
Java
System.out.println(280.0 / 16); // 17.5 cm
C#
Console.WriteLine(280m / 16); // 17.5 cm
