Definitions of TNS Instructions
CEFR (000277). Convert Extended to Floating, Rounded. The four-word floating-point
quantity in DCBA is converted to a two-word floating-point quantity. The new quantity
is rounded according to the contents of truncated bit 7 of C. DCBA is deleted, and the
two-word result is pushed onto the stack.
CEI (000337). Convert Extended to Integer. The extended floating-point quantity in
DCBA is converted to a single-word signed integer. CBA is deleted, and the single-
word result is pushed onto the stack. Overflow is set if the value of the operand was
greater than 32767 or less than –32768. Condition Code is set on the result.
CEIR (000316). Convert Extended to Integer, Rounded. The extended floating-point
quantity in DCBA is converted to a single-word signed quantity, with rounding
according to the contents of the most significant fractional bit. CBA is deleted, and the
single-word result is pushed onto the stack. Overflow is set if the value of the operand
was greater than 32767 or less than –32768. Condition Code is set on the result.
CEQ (000322). Convert Extended to Quadruple. The extended floating-point quantity
in DCBA is converted to a quadrupleword integer in DCBA. Overflow is set if the value
of the operand was greater than 2
63
–1 or less than –2
63
. Condition Code is set on the
result.
CEQR (000323). Convert Extended to Quadruple, Rounded. The extended floating-
point quantity in DCBA is converted to a quadrupleword integer in DCBA, with rounding
according to the contents of the most significant fractional bit. Overflow is set if the
value of the operand was greater than 2
63
–1 or less than –2
63
. Condition Code is set
on the result.
CFD (000312). Convert Floating to Double. The floating-point quantity in BA is
converted to a doubleword signed integer in BA. Overflow is set if the value of the
operand was greater than 2
31
–1 or less than –2
31
. Condition Code is set on the result.
CFDR (000313). Convert Floating to Double, Rounded. The floating-point quantity in
BA is converted to a doubleword signed integer in BA, with rounding according to the
contents of the most significant fractional bit. Overflow is set if the value of the
operand was greater than 2
31
–1 or less than –2
31
. Condition Code is set on the result.
CFE (000325). Convert Floating to Extended. The floating-point quantity in BA is
converted to an extended floating-point quantity. BA is deleted, and the four-word
result is pushed onto the stack.
CFI (000311). Convert Floating to Integer. The floating-point quantity in BA is
converted to a single-word signed integer. A is deleted, and the single-word result is
pushed onto the stack. Overflow is set if the value of the operand was greater than
32767 or less than –32768. Condition Code is set on the result.
CFIR (000310). Convert Floating to Integer, Rounded. The floating-point quantity in
BA is converted to a single-word signed integer, with rounding according to the
contents of the most significant fractional bit. A is deleted, and the single-word result is
pushed onto the stack. Overflow is set if the value of the operand was greater than
32767 or less than –32768. Condition Code is set on the result.
