| ALGORITHM DESCRIPTION: |
| |
| We are using the next identity : pow(x,y) = 2^(y * log2(x)). |
| |
| 1) log2(x) calculation |
| Here we use the following formula. |
| Let |x|=2^k1*X1, where k1 is integer, 1<=X1<2. |
| Let C ~= 1/ln(2), |
| Rcp1 ~= 1/X1, X2=Rcp1*X1, |
| Rcp2 ~= 1/X2, X3=Rcp2*X2, |
| Rcp3 ~= 1/X3, Rcp3C ~= C/X3. |
| Then |
| log2|x| = k1 + log2(1/Rcp1) + log2(1/Rcp2) + log2(C/Rcp3C) + |
| log2(X1*Rcp1*Rcp2*Rcp3C/C), |
| where X1*Rcp1*Rcp2*Rcp3C = C*(1+q), q is very small. |
| |
| The values of Rcp1, log2(1/Rcp1), Rcp2, log2(1/Rcp2), |
| Rcp3C, log2(C/Rcp3C) are taken from tables. |
| Values of Rcp1, Rcp2, Rcp3C are such that RcpC=Rcp1*Rcp2*Rcp3C |
| is exactly represented in target precision. |
| |
| log2(X1*Rcp1*Rcp2*Rcp3C/C) = log2(1+q) = ln(1+q)/ln2 = |
| = 1/(ln2)*q - 1/(2ln2)*q^2 + 1/(3ln2)*q^3 - ... = |
| = 1/(C*ln2)*cq - 1/(2*C^2*ln2)*cq^2 + 1/(3*C^3*ln2)*cq^3 - ... = |
| = (1 + a1)*cq + a2*cq^2 + a3*cq^3 + ..., |
| where |
| cq=X1*Rcp1*Rcp2*Rcp3C-C, |
| a1=1/(C*ln(2))-1 is small, |
| a2=1/(2*C^2*ln2), |
| a3=1/(3*C^3*ln2), |
| ... |
| Log2 result is split by three parts: HH+HL+HLL |
| |
| 2) Calculation of y*log2(x) |
| Split y into YHi+YLo. |
| Get high PH and medium PL parts of y*log2|x|. |
| Get low PLL part of y*log2|x|. |
| Now we have PH+PL+PLL ~= y*log2|x|. |
| |
| 3) Calculation of 2^(y*log2(x)) |
| Let's represent PH+PL+PLL in the form N + j/2^expK + Z, |
| where expK=7 in this implementation, N and j are integers, |
| 0<=j<=2^expK-1, |Z|<2^(-expK-1). Hence |
| 2^(PH+PL+PLL) ~= 2^N * 2^(j/2^expK) * 2^Z, |
| where 2^(j/2^expK) is stored in a table, and |
| 2^Z ~= 1 + B1*Z + B2*Z^2 ... + B5*Z^5. |
| We compute 2^(PH+PL+PLL) as follows: |
| Break PH into PHH + PHL, where PHH = N + j/2^expK. |
| Z = PHL + PL + PLL |
| Exp2Poly = B1*Z + B2*Z^2 ... + B5*Z^5 |
| Get 2^(j/2^expK) from table in the form THI+TLO. |
| Now we have 2^(PH+PL+PLL) ~= 2^N * (THI + TLO) * (1 + Exp2Poly). |
| Get significand of 2^(PH+PL+PLL) in the form ResHi+ResLo: |
| ResHi := THI |
| ResLo := THI * Exp2Poly + TLO |
| Get exponent ERes of the result: |
| Res := ResHi + ResLo: |
| Result := ex(Res) + N. */ |
