or fsin perform the calculation by some other instructions? that means whether we can program to compute the math function: sin(x) in assembly language but without employing the instruction fsin?
you can approximate any function by Tailor series... as well as sin. but CPU does it in hardware.
thanks for your reply! but i am still wondering how the fpu hardware can perform such kind of complex computation by electronic circuit. :red
by the way qlmi,
welcome on board. of course every trigonometric function in hardware as in software is only approximation but with a different accuracy. hardware circuits do it faster... but i'm sure both this ways are based on Tailor series with a limited num of elements in serie to perform needed accuracy (e.g. 80bit or 64bit)
OK, got it!
