48 | * DESCRIPTION |
---|
49 | * The _isnanf4 function returns a vector in which each element indicates |
---|
50 | * if the corresponding element of x is NaN. |
---|
51 | * |
---|
52 | * On the SPU, this function always returns 0, since NaNs are not |
---|
53 | * supported. |
---|
54 | * |
---|
55 | * RETURNS |
---|
56 | * UINT_MAX (0xFFFFFFFF) if the element of x is a NaN |
---|
57 | * 0 (0x00000000) otherwise (always on the SPU) |
