## Function Documentation

### void misspack (float \* fld, g2int ndpts, g2int idrsnum, g2int \* idrstmpl, unsigned char \* cpack, g2int \* lcpack)

Pack a data field using a complex packing algorithm. This funciton supports GRIB2 complex packing templates with or without spatial differences (See `Template 5.2` and `Template 5.3`).

This function fills in GRIB2 Data Representation template arrays with the appropriate values.

**Parameters**

*fld* Contains the data values to pack \
 *ndpts* The number of data values in array fld \
 *idrsnum* Data Representation Template number. Must equal 2 or 3. \
 *idrstmpl* Contains the array of values for Data Representation Template 5.2 or 5.3.

- •

  0 Reference value - ignored on input, set by misspack routine.

- •

  1 Binary Scale Factor - used on input.

- •

  2 Decimal Scale Factor- used on input.

- •

  6 Missing value management.

- •

  7 Primary missing value.

- •

  8 Secondary missing value.

- •

  16 Order of Spatial Differencing (1 or 2).

*cpack* The packed data field (character\*1 array). \
 *lcpack* length of packed field cpack.
