You would be far better asking on the sage-support mailing list. Just

My suggestion is:
x=var('x')
rf = RealField(prec=10) #10 bits
g(x) = -rf(-0.1) * x^4
print g
print g(1.2345)
but before try:
preparse('g(x) = -0.1 * x^4')
It seems that Sage always prints the full and correct representation
of the RealNumber and not just an approximation. In this matter Sage
is
