 Floating-point arithmetic instructions with one or two source operands use the
-R-type format with the OP-FP major opcode.  FADD.S, FSUB.S,
-FMUL.S, and FDIV.S perform single-precision floating-point addition,
-subtraction, multiplication, and division, respectively, between {\em rs1} and
-{\em rs2}, writing the result to {\em rd}.
-FSQRT.S computes the square root of {\em rs1} and writes the
-result to {\em rd}.
+R-type format with the OP-FP major opcode.  FADD.S and FMUL.S perform

+between {\em rs1} and {\em rs2}. FSUB.S performs the single-precision
+floating-point subtraction of {\em rs2} from {\em rs1}.  FDIV.S performs the

+computes the square root of {\em rs1}.  In each case, the result is written to
+{\em rd}.
 
 The 2-bit floating-point format field {\em fmt} is encoded as shown in
 Table~\ref{tab:fmt}.  It is set to {\em S} (00) for all instructions in
