[Quantlib-users] Query on gamma

[Ashish B. <ash...@gm...>]

Hi,

I am calculating the option gamma using the following functions:
engine = FdBlackScholesVanillaEngine
Process = BlackScholesMertonProcess
payoff = PlainVanillaPayoff with american option
gamma function = option.gamma()

For a few of the options, I am getting the gamma more than 1, up to 13. I
want to know if the above function returns the gamma in percentage terms or
decimal. Should I be dividing the gamma by 100 to get the correct value?

Regards,
Ashish
