You can use numerical_integral instead of integral

numerical_integral(x^x,1,2)

or explicitly order a numerical answer

integral(x^x,x,1,2).n()

Equivalently, feed the whole expression to $N$

sage: N(integral(x^x,x,1,2)) #2.0504462345347307

Also, the same syntax $N$ exists in SymPy and the equivalent of $f.n()$ in SymPy is $f.evalf()$
