$FIXL

$FIXL converts a FIXED value to an unsigned INT value.

fixed-expression

is a FIXED expression, which $FIXL treats as a FIXED expression, ignoring any

implied decimal point.

If the result cannot be represented in an unsigned 16-bit integer, $FIXL traps if

overflow traps are enabled (see Section 13, Hardware Indicators); otherwise, $FIXL

ignores the problem.

$FIXR

$FIXR converts its argument to a FIXED value and rounds the result.

Example 15-36. $FIXI Routine

INT intnum;

FIXED fixnum := %177777F;

intnum := $FIXI (fixnum); ! Return -1

pTAL privileged procedure No

Can be executed only by privileged procedures No

Sets condition code No

Sets $CARRY No

Sets $OVERFLOW Yes

Example 15-37. $FIXL Routine

INT intnum;

FIXED fixnum := 32767F;

intnum := $FIXL (fixnum); ! Return 32,767
