[Description]
Checks whether the argument is signed infinity.

[Explanation]
is_sinf returns <A HREF="$$LINK(alloc.h/Bool)">TRUE</A> if <I>x</I> is a signed infinity
(i.e. <A HREF="$$LINK(POSITIVE_INF)">POSITIVE_INF</A> or <A HREF="$$LINK(NEGATIVE_INF)">NEGATIVE_INF</A>),
else returns <A HREF="$$LINK(alloc.h/Bool)">FALSE</A>.
This function is an alias for TIOS function
originally called <A HREF="$$LINK(is_float_signed_infinity)">is_float_signed_infinity</A>.
