| 1043 | We are building perl with long double support and are on an AIX OS | |
| 1044 | afflicted with a powl() function that wrongly returns NaNQ for any | |
| 1045 | negative base. This was reported to IBM as PMR #23047-379 on | |
| 1046 | 03/06/2006. The problem exists in at least the following versions | |
| 1047 | of AIX and the libm fileset, and no doubt others as well: | |

| 1049 | AIX 4.3.3-ML10 bos.adt.libm 4.3.3.50 | |

| 1051 | AIX 5.2.0 bos.adt.libm 5.2.0.85 | |
| 1052 | ||
| 1053 | So, until IBM fixes powl(), we provide the following workaround to | |
| 1054 | handle the problem ourselves. Our logic is as follows: for | |
| 1055 | negative bases (left), we use fmod(right, 2) to check if the | |
| 1056 | exponent is an odd or even integer: | |
| 1057 | ||
| 1058 | - if odd, powl(left, right) == -powl(-left, right) | |
| 1059 | - if even, powl(left, right) == powl(-left, right) | |
| 1060 | ||
| 1061 | If the exponent is not an integer, the result is rightly NaNQ, so | |
