evaluating an expression

started to use open source mathematical software. And i have some questions since i can not find in google what i am searching for (maybe i am a bad searcher :S).
The thing is if i write in maple (with predefined F, M, q and Q):
Sum('F[ix]', 'i' = 1 .. n) = 0; '-2*F*cos(45*deg)-3*Q+4*RB*cos(45*deg)-RB*sin(45*deg)-M = 0'; evalf(solve(%, RB))
RB := 19.51
And in Sage:
[23/3*sqrt(2) + 26/3 == 23/3*sqrt(2) + 26/3]
Now i do not find any equivalent to evalf in sage. Could someone help me, please?
