$FIXEDTOASCII

fixed-expression

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

implied decimal point.

If the result cannot be represented in a signed doubleword, $FIXD traps if overflow

traps are enabled (see Section 13, Hardware Indicators); otherwise, $FIXD ignores the

problem.

$FIXEDTOASCII

$FIXEDTOASCII converts the absolute value of a FIXED value to an ASCII value.

qvalue input

FIXED(*):value

is a quadrupleword integer value to convert to ASCII digits.

bufferaddr input

BADDR:value

is the byte address at which to write the ASCII digits.

maxdigits input

uINT:value

is the maximum number of ASCII digits to write at bufferaddr.

Example 15-33. $FIXD Routine

INT(32) dblnum;

FIXED fixnum := 1234F;

dblnum := $FIXD (fixnum); ! Return 1234D
