Fix cproj handling of (finite, NaN) arguments (bug 15531).
|
|
|
147e83 |
|
|
|
147e83 |
* math/s_cprojf.c (__cprojf): Only return an infinity if one part of
|
|
|
147e83 |
argument is infinite.
|
|
|
147e83 |
|
|
|
147e83 |
This patch is added so as to compile isnan multiarch implementation
|
|
|
147e83 |
successfully since __GI___isnanf is missing.This wll be fixed later in master.
