Case contract

Convert a decimal price string to an American moneyline string. Prices at or below 1 return "invalid". For d >= 2 the line is "+" followed by 100 * (d - 1); for d < 2 it is "-" followed by 100 / (d - 1). The magnitude is computed exactly from the decimal text and rounded half up to an integer. Evens (2.00) is "+100".

Why this case matters

Sportsbooks display the same price in decimal and American formats and must agree at every boundary.
