life of the annuity. Typically, pmt contains principal and interest but no
other fees or taxes.

Optionalfv: number = 0The future value, or a cash balance you want to
attain after the last payment is made. If fv is omitted, it is assumed to
be 0 (the future value of a loan, for example, is 0).
Optionaltype: 0 | 1 = 0The number 0 or 1 and indicates when payments are
due. Set type equal to 0 or omitted if payments are due at the end of the
period. Set type equal to 1 if payments are due at the beginning of the
