[sage-support] Sage sgn to Sympy sign

2011-10-13 Thread CDSousa
Hi, Sage uses a dictionary to translate Sage function names to SymPy ones when they are different. Signal function is called "sgn" in Sage and "sign" in Sympy but the respective translation is not in the dictionary, and a error is issued if one tries to do something like: x = var('x'); sgn(x)._
