| * clog(-0 + i0) returns -inf + ipi and raises the divide-by-zero floating-point exception. |
| * clog(+0 + i0) returns -inf + i0 and raises the divide-by-zero floating-point exception. |
| * clog(x + i inf) returns +inf + ipi /2, for finite x. |
| * clog(x + iNaN) returns NaN + iNaN and optionally raises the invalid floating-point exception, for finite x. |
| * clog(-inf + iy) returns +inf + ipi , for finite positive-signed y. |
| * clog(+inf + iy) returns +inf + i0, for finite positive-signed y. |
| * clog(-inf + i inf) returns +inf + i3pi /4. |
| * clog(+inf + i inf) returns +inf + ipi /4. |
| * clog(+/-inf + iNaN) returns +inf + iNaN. |
| * clog(NaN + iy) returns NaN + iNaN and optionally raises the invalid floating-point exception, for finite y. |
