Ideal Rise Height = 180mm
Number of Rises = Total Rise ÷ Ideal Rise Height (rounded up)
Rise Height = Total Rise ÷ Number of Rises
Number of Goings = Number of Rises - 1
Base Length = Number of Rises × Total Going
Stringer Length = √(Total Rise² + Base Length²)
Slope Angle = atan(Total Rise ÷ Base Length) × (180 ÷ π)
