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,
isieee
 = 1
 implies that all the features of the IEEE standard that we rely on are implemented. On exit,
isieee
 = 0
 implies that some the features of the IEEE standard that we rely on are missing.
