1037 | We are building perl with long double support and are on an AIX OS | |
1038 | afflicted with a powl() function that wrongly returns NaNQ for any | |
1039 | negative base. This was reported to IBM as PMR #23047-379 on | |
1040 | 03/06/2006. The problem exists in at least the following versions | |
1041 | of AIX and the libm fileset, and no doubt others as well: | |

1043 | AIX 4.3.3-ML10 bos.adt.libm 4.3.3.50 | |
1044 | AIX 5.1.0-ML04 bos.adt.libm 5.1.0.29 | |
1045 | AIX 5.2.0 bos.adt.libm 5.2.0.85 | |
1046 | ||
1047 | So, until IBM fixes powl(), we provide the following workaround to | |
1048 | handle the problem ourselves. Our logic is as follows: for | |
1049 | negative bases (left), we use fmod(right, 2) to check if the | |
1050 | exponent is an odd or even integer: | |
1051 | ||
1052 | - if odd, powl(left, right) == -powl(-left, right) | |
1053 | - if even, powl(left, right) == powl(-left, right) | |
1054 | ||
1055 | If the exponent is not an integer, the result is rightly NaNQ, so | |
1056 | we just return that (as NV_NAN). | |
