13 EA <- (RA|0) + EXTS(D)
14 FRT <- DOUBLE(MEM(EA, 4))
18 Let the effective address (EA) be the sum (RA|0)+D.
19 The word in storage addressed by EA is interpreted as
20 a floating-point single-precision operand. This word is
21 converted to floating-point double format (see
22 page 138) and placed into register FRT.
24 Special Registers Altered:
28 # Load Floating-Point Single Indexed
37 FRT <- DOUBLE(MEM(EA, 4))
41 Let the effective address (EA) be the sum (RA|0)+(RB).
43 The word in storage addressed by EA is interpreted as
44 a floating-point single-precision operand. This word is
45 converted to floating-point double format (see
46 page 138) and placed into register FRT.
