double complex clog(double complex z);
float complex clogf(float complex z);
long double complex clogl(long double complex z);
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.
These functions shall compute the complex natural (base e) logarithm of z, with a branch cut along the negative real axis.
These functions shall return the complex natural logarithm value, in the range of a strip mathematically unbounded along the real axis and in the interval [-i, +i] along the imaginary axis.
No errors are defined.
