1066 | We are building perl with long double support and are on an AIX OS | |
1067 | afflicted with a powl() function that wrongly returns NaNQ for any | |
1068 | negative base. This was reported to IBM as PMR #23047-379 on | |
1069 | 03/06/2006. The problem exists in at least the following versions | |
1070 | of AIX and the libm fileset, and no doubt others as well: | |
1071 | ||
1072 | AIX 4.3.3-ML10 bos.adt.libm 4.3.3.50 | |
1073 | AIX 5.1.0-ML04 bos.adt.libm 5.1.0.29 | |
1074 | AIX 5.2.0 bos.adt.libm 5.2.0.85 | |
1075 | ||
1076 | So, until IBM fixes powl(), we provide the following workaround to | |
1077 | handle the problem ourselves. Our logic is as follows: for | |
1078 | negative bases (left), we use fmod(right, 2) to check if the | |
1079 | exponent is an odd or even integer: | |
1080 | ||
1081 | - if odd, powl(left, right) == -powl(-left, right) | |
1082 | - if even, powl(left, right) == powl(-left, right) | |
1083 | ||
1084 | If the exponent is not an integer, the result is rightly NaNQ, so | |
1085 | we just return that (as NV_NAN). | |
