Description
The
p?lachkieee
function
performs a simple check to make sure that the features of the IEEE standard are implemented. In some implementations, p?lachkieee
may not return.This is a ScaLAPACK internal
function
and arguments are not checked for unreasonable values. Input Parameters
- rmax
- (local).The overflow threshold(=.?lamch('O'))
- rmin
- (local).The underflow threshold(=.?lamch('U'))
Output Parameters
- isieee
- (local).On exit,implies that all the features of the IEEE standard that we rely on are implemented. On exit,isieee= 1implies that some the features of the IEEE standard that we rely on are missing.isieee= 0
