+Description:
+
+    Let the effective address (EA) be the sum (RA)+D.
+
+    The word in storage addressed by EA is interpreted as
+    a floating-point single-precision operand. This word is
+    converted to floating-point double format (see
+    page 138) and placed into register FRT.
+
+    EA is placed into register RA.
+
+    If RA=0, the instruction form is invalid.
