The data transfer instructions move floating-point, integer, and BCD values between memory and the floating point registers. x86 Assembly/Floating Point The ALU is only capable of dealing with integer values. While integers are sufficient for some applications, it is often necessary Operands can be signed integers (word or dword), or floating point (real4, real8 or tbyte). All arithmetic is tbyte (80 bits) internally. fadd ; add st(0) to st The instructions in this category are FLD, FST, FSTP, and FXCH. The FLD instruction always pushes its operand onto the floating point stack. The FSTP For example, the integer PowerPC assembly code to add registers 1 and 2 into registers 1 and 2 into floating-point register 3 is "fadd fr3,fr1,fr2". x86 Note: FADD without operands can also be used with the MASM assembler but such an instruction is coded as FADDP ST(1),ST(0). Exception flags: Stack Fault, The FIADD instructions convert an integer source operand to double extended-precision floating-point format before performing the addition.
