<?php

// Result, Settlement, Maturity, Rate, Yield, Redemption, Frequency, Basis
// On the result line, the value is ODS's calculation.
//     This agrees with Gnumeric, PhpSpreadsheet, and the published algorithm at:
//https://support.office.com/en-us/article/price-function-3ea9deac-8dfa-436f-a7c8-17ea02c21b0a.
// The commented-out value on the next line is Excel's result.
// I do not know how best to reconcile the different results.
// The problem seems restricted to basis codes 2 and 3.
