16 .Fn csqrtf "float complex z"
17 .Ft long double complex
18 .Fn csqrtl "long double complex z"
20 These functions compute the complex square root of
22 with a branch cut along the negative real axis.
24 These functions return the complex square root value, in the
25 range of the right half-plane (including the imaginary axis).
