s_sincosf.h: Change pio4 type to float [BZ #28713]
|
||
|
|
|
||
|
|
s_cosf.c and s_sinf.c have
|
||
|
|
|
||
|
|
if (abstop12 (y) < abstop12 (pio4))
|
||
|
|
|
||
|
|
where abstop12 takes a float argument, but pio4 is static const double.
|
||
|
|
pio4 is used only in calls to abstop12 and never in arithmetic. Apply
|
||
|
|
|
||
|
|
-static const double pio4 = 0x1.921FB54442D18p-1;
|
||
|
|
+static const float pio4 = 0x1.921FB6p-1f;
