Calculate the square root of a given complex number, with
non-negative real part, and with a branch cut along the
negative real axis. (That means that csqrt(−1+eps*I) will be
close to I while csqrt(−1−eps*I)
will be close to −I, if
eps is a small positive real number.)
VERSIONS
These functions first appeared in glibc in version
2.1.
