Dear ROOT Support,
I would like to place a lower limit on a parameter in my function, while leaving the upper limit free. Is this possible?
The formula for my function is:
TFormula mypol4(“mypol4”," * ( 1 + *x + *x^2 + *x^3 + *x^4 )");
I would like to set limit so that the parameter  is not negative.
Thanks very much.
