The current helper uses bisection, while Microsoft’s page describes a Newton method. Their stopping and boundary results are separate compatibility questions. The worked zero-yield example isolates the coupon and accrual arithmetic from discount powers. Calendar seams, long/short-period branches and residual numerical differences remain open where the recorded reports say so. The family combines a credited Apache-licensed ExcelFinancialFunctions translation in its odd-first kernel and calendar helpers with project-owned kernels and changes guided by recorded Excel answers.\n\n\n", "quirks": "\nBasis defaults to zero: 0 US 30/360, 1 actual/actual, 2 actual/360, 3 actual/365, 4 European 30/360.
