acb_real_sqrtpos
Synopsis
#include <flint/acb.h>The square root on [0, +\infty), extended to the principal complex square root. For a real z without analytic, only the nonnegative part is used, as by arb_sqrtpos. This is the function to integrate \sqrt{f(x)} when f(x) \ge 0 is known: unlike acb_sqrt_analytic, it creates no spurious imaginary parts [\pm \varepsilon] i when an enclosure of f(x) straddles 0.
