Example

This example defines a double fractional value, converts it into 1-byte fixed, 1-byte fraction value, and then converts it back into double

L_INT LICCProfile_DoubleToU8Fixed8NumberExample() 
{ 
   L_DOUBLE dNumber; 
   L_IccU8Fixed8Number uIccNumber; 
   dNumber = 1.9858; 
   uIccNumber = ( L_IccU8Fixed8Number) LICCProfile::DoubleToU8Fixed8Number(dNumber); 
   dNumber = LICCProfile::U8Fixed8NumberToDouble (uIccNumber); 
   return SUCCESS;
