sets or gets the floating point exception mode
mod = ieee() ieee(mod)
integer scalar whose possible values are 0, 1 or 2
ieee()
returns the current floating point exception mode.
floating point exception produces an error.
%inf
and %nan
special values can be
used in this mode without error. For instance, %inf/%inf
,
%inf-%inf
or %inf/%nan
are known
operations.
ieee(mod)
sets the current floating point exception mode to
mod
.
![]() | The default initial mode is 2. This default value may be set in any of the following ways:
|
![]() | Floating point exception arising inside some library algorithms are not yet handled
by ieee modes. |
ieee(1); 1/0 ieee(2); 1/0, log(0) | ![]() | ![]() |
Version | Description |
6.0.0 | 2 is now the initial mode value. |
