解释：
There are 184 days between coupon payments and 104 days between the last coupon and the settlement date. The accrued interest is
3×104/184 =1.6957
The cash price is 98 + 1.6957 = 99.6957.
题目问：US treasury bond的价格是98，在6月27日交割，年coupon rate是6%，付息日是每年的3月15日和9月15日，求cash price是多少？
付息日之间是184天，最后一次付息到交割是104天，
accrued interest=3*104/184=1.6957
cash price=98+1.6957=99.6957
