pow2.cpp 88 L_x = Result of the Pow2() computation (Word32)
103 This function computes L_x = pow(2.0, exponent.fraction)
105 The function Pow2(L_x) is approximated by a table and linear interpolation.
109 3- L_x = table[i]<<16 - (table[i] - table[i+1]) * a * 2
110 4- L_x = L_x >> (30-exponent) (with rounding)
131 Word32 L_x;
133 L_x = L_mult (fraction, 32); // L_x = fraction<<6
134 i = extract_h (L_x); // Extract b10-b16 of fractio
