Summary

0000320: For MX shaded text NaN errors are required

Description

The acos() RETURN VALUE section states, in MX shaded text:

    "If x is +/-Inf, a domain error shall occur, and either a NaN
    (if supported), or an implementation-defined value shall be
    returned."

Since this is in MX shading, NaN is supported and the "or an
implementation-defined value" part is redundant.

The same problem occurs for some other maths functions as well.

Desired Action

At
page 102 line 3862 section acos,
page 104 line 3918 section acosh,
page 126 line 4586 section asin,
page 138 line 4897 section atanh,
page 227 line 7611 section cos,
page 391 line 12638 section fmod,
page 391 line 12640 section fmod,
page 1225 line 38477 section remainder,
page 1230 line 38586 section remquo,
page 1402 line 43816 section sin,
page 1417 line 44254 section sqrt,
and
page 1535 line 47781 section tgamma
change

    "and either a NaN (if supported), or an implementation-defined
    value shall be returned"

to
    "and a NaN shall be returned"

Note to the editor: similar text may appear elsewhere on these
pages with partial MX shading. It is only the cases where the
text is entirely MX shaded that should be modified.
