Case contract

Convert a decimal price (> 1, else "invalid") to an Asian odds style. hk: d - 1. malay: d - 1 when d <= 2, else -1 / (d - 1). indo: d - 1 when d >= 2, else -1 / (d - 1). Other styles return "invalid style". Values are rounded half away from zero to two decimals and formatted with a leading "-" for negatives.
