+This routine looks the log2 value in the table considering LOG2_LOG_TABLE_SIZE+1 MSBs.
+As the MSB is always 1, only next LOG2_OF_LOG_TABLE_SIZE MSBs are used for table lookup.
+Next 16 MSBs are used for interpolation.
+Inputs:
+N - number to which log10 has to be found.
+qN - q format of N
+log10N - address where log10(N) will be written.
+qLog10N - address where log10N qformat will be written.
