The forwarexchange rate is given by:FJPYAUSJPYAU+rJPYτ1+rAU=82.421+0.0015903601+0.049590360=82.42×0.98815=81.443.The forwarpoints are follows:100 × (F × S) = 100 × (81.443 – 82.42) = 100 × (–0.977) = –97.7.Because the spot exchange rate is quotewith two cimplaces, the forwarpoints are scale100. 那个带e的公式是什么时候用的？
