| 1045 | We are building perl with long double support and are on an AIX OS | |
| 1046 | afflicted with a powl() function that wrongly returns NaNQ for any | |
| 1047 | negative base. This was reported to IBM as PMR #23047-379 on | |
| 1048 | 03/06/2006. The problem exists in at least the following versions | |
| 1049 | of AIX and the libm fileset, and no doubt others as well: | |

| 1053 | AIX 5.2.0 bos.adt.libm 5.2.0.85 | |
| 1054 | ||
| 1055 | So, until IBM fixes powl(), we provide the following workaround to | |
| 1056 | handle the problem ourselves. Our logic is as follows: for | |
| 1057 | negative bases (left), we use fmod(right, 2) to check if the | |
| 1058 | exponent is an odd or even integer: | |
| 1059 | ||
| 1060 | - if odd, powl(left, right) == -powl(-left, right) | |
| 1061 | - if even, powl(left, right) == powl(-left, right) | |
| 1062 | ||
| 1063 | If the exponent is not an integer, the result is rightly NaNQ, so | |
| 1064 | we just return that (as NV_NAN). | |
