D8 C0+i, FADD ST(0), ST(i) In some assemblers, the mnemonic for this instruction is FADD rather than FADDP.) F Means finite floating-point value.

FADD. add floating-point. faddp. FADDP. add floating-point and pop. The FADD instruction adds the values in Fn and Fm and places the result in Fd . The FSUB instruction subtracts the value in Fm from the value in Fn and I Means integer. * Indicates floating-point invalid-arithmetic-operand (#IA) exception. This instruction's operation is the same in non-64-bit modes and In some assemblers, the mnemonic for this instruction is FADD rather than FADDP.) The FIADD instructions convert an integer source operand to extended-real FADD/FADDP/FIADD—Add In some assemblers, the mnemonic for this instruction is FADD rather than FADDP.) F Means finite floating-point value. The destination operand must be one of the other FPU registers. The last form above, FADD with a memory operand, adds a 32 or 64 bit floating point variable to14.4.6.1 The FADD and FADDP Instructions The first two forms are equivalent. They pop the two values on the top of stack, add them, and push their sum back
