The POD section "Real-valued asin and acos" seems to mix up sin()/cos()
with asin()/acos(). The text in the section says that asin() and acos()
"may return complex numbers even when real numbers would be enough and
correct". Maybe so, but that is not what the examples illustrate.
Furthermore, the poorly written example
printf "%.20f", cos(1e-6)**2+sin(1e-6)**2,"\n";
gives the warning "Redundant argument in printf at ..."
