WebAccording to your answer: "Fixed point division is integer division, there's not much to do about it." I think you're wrong. Finding the arithmetic reciprocal is a bit simpler than dividing, because the value of the dividend in the first case is predetermined, i.e. equal to 1.0 (in the interpretation of integers as fixed point values).

WebNov 25, 2024 · Convert back from Q64 fixed point to 32bit integer 0x5555555500 >> 32 = 0x55 = 85 in assembly; This is working fine, but now, I want to divide 2 unknown number by each other. In order to do this, using the algorithm above, first I must calculate a reciprocal value of the y in assembly, not by hand. The division by a constant D is equivalent to the multiplication by its reciprocal. Since the denominator is constant, so is its reciprocal (1/D). Thus it is possible to compute the value of (1/D) once at compile time, and at run time perform the multiplication N·(1/D) rather than the division N/D. In floating-point arithmetic the use of (1/D) presents little problem, but in integer arithmetic the reciprocal will always evaluate to zero (assuming D > 1).

"WebThe Q15 numbers as hexadecimal integers will be a = 0x0400 and b = 0x2000. In step 1, a becomes 0x02000000 in Q30. In step 2, divide 0x02000000 by 0x2000 to get c = 0x1000 which is 4096 in decimal. As a check, find 4096/32768 = 0.125, the expected result. In C language code, fixed point Q15 division can be coded as follows: " - Fixed point reciprocal
