3.4.133 –xia[={widestneed|strict}]

(SPARC) Enable interval arithmetic extensions and set a suitable floating-point environment.

The default if not specified is -xia=widestneed.

Fortran 95 extensions for interval arithmetic calculations are detailed in the Interval Arithmetic Programming Reference. See also 3.4.136 –xinterval[={widestneed|strict|no}].

The -xia flag is a macro that expands as follows:

-xia or-xia=widestneed

-xinterval=widestneed -ftrap=%none -fns=no -fsimple=0

-xia=strict

-xinterval=strict -ftrap=%none -fns=no -fsimple=0
