New Post: Excel functions: PPMT,IPMT,PMT,CUMIPMT,CUMPRINC

Dear Team,

We want to our application to support list of excel functions. Among those I could find that below functions are available in Math.Net library.
NormInv,NormDist,NormSDist,NormSInv,BetaDist,BetaInv,

I am unable to find any equivalent for following excel function:
PPMT,IPMT,PMT,CUMIPMT,CUMPRINC

Could you please let me know if Math.Net supports these functions?

Thanks
Shyam
