x^y with x,y real numbers ?

[Francesco Montorsi]

Hi all,
    looking in the GMP manual for the latest version, I cannot find any MPF
function like

mpf_pow(mpf_t rop, mpf_t base, mpf_t exp)

I know that in MPFR there's one, but is there a way to compute x^y (with
both x and y mpf_t types) in simple GMP, without using MPFR ?

Thanks,
FM
