塗偉誠Python與Javascript與EXCEL IRR函數比較
pmt = [0,0,0,0] #塗偉誠程式設計586設定串列list pmt[0]=float(input('躉繳金額: ')) for nper in range(1,4): pmt[nper] = float(input('第'+str(nper)+'期回收: ')) def npv(rate): y = - pmt[0] for j in range(1,4): y = y + pmt[j]/(1+rate)**j return y a, b, gap, f = 0.0, 1.0, 9.0, 9.0 maxerror = 0.000001 loopNumber = 1 while (gap > maxerror and abs(f) > maxerror and loopNumber maxerror and gap > maxerror): if ( f>0 ): a = c else: b = c gap = b-a; print('塗偉誠報酬率: ', c) print('塗偉誠淨現值: ', f) print('塗偉誠迴圈次數: ', loopNumber) 心得：這學期我學習到了很多東西,收穫滿滿。
