These constants define the conversion types to convert a HIGCOMPLEXOBJ object to a HIGEAR object.
| IG_CO_OBJ_CONV_TYPE_REAL | 0 | Use the real data. |
| IG_CO_OBJ_CONV_TYPE_IMAGINARY | 1 | Use the imaginary data. |
| IG_CO_OBJ_CONV_TYPE_MAGNITUDE | 2 | Use the magnitude data. |
| IG_CO_OBJ_CONV_TYPE_PHASE | 3 | Use the phase data. |
| IG_CO_OBJ_CONV_TYPE_LOGMAG | 4 | Use the logarithm (10) of the magnitude data. |
| IG_CO_OBJ_CONV_TYPE_LOGMAGP1 | 5 | Use the logarithm (10) of (magnitude data + 1). |
| IG_CO_OBJ_CONV_TYPE_MAGSQ | 6 | Use the square of the magnitude. |
| IG_CO_OBJ_CONV_TYPE_LOGMAGSQ | 7 | Use the logarithm (10) of the square of the magnitude. |
| IG_CO_OBJ_CONV_TYPE_LOGMAGSQP1 | 8 | Use the logarithm (10) of (square of the magnitude + 1). |
