Yes, try
I knew it
my question is about the list referred in help
constants in the list. If the list is empty it uses a list of common
constants.
is not pi in the list?
and now I think there is a little bug
if I type
text=surdtext(pi,{pi})
text=surdtext(3 pi,{pi})
text=surdtext(4pi,{pi})
then GG creates text,text_1,text_2

you are right
opening an empty worksheet
typing my three sysntaxes I have problem ever
opening an empty worksheet then open and close the CAS window (CAS initialising change to GIAC); I have not the problem
also note that SurdText currently tries to reconstruct a formula from decimal number, that's in general impossible (there might be a fraction, square root and multiple of pi very close to each other). With FormulaText you can use the definition of the input number; for instance a=81pi/2, FormulaText[a]
