[Ipopt] How to change adouble variable to double and round function

[Zhaori Bi]

Hi guys,

I am using ipopt c++ interface now, I found the variable is defined as
adouble class. which defind
1.234567 as 1.234567(a). Do you have any idea how to convert this to a
double number?

And Do you guys know how to round the adouble number since round() function
only work with double/float number.

Thank you for the rely!
