This HP-38E/38C program calculates the price per $100 and the dollar value of U. S. Treasury Bills given the face amount, the quote and maturity dates and the bid and ask quotations (as a percent yield). The price per $100 and the dollar value may be calculated on either bid or ask quotation alone if only one is known.
