CRNum* cr_num_dup | ( | CRNum const * | a_this | ) |
cr_num_dup: : the instance of CRNum to duplicate.
Duplicates an instance of CRNum
Returns the newly created (duplicated) instance of CRNum. Must be freed by cr_num_destroy().

gboolean cr_num_is_fixed_length | ( | CRNum const * | a_this | ) |
cr_num_is_fixed_length: : the current instance of CRNum .
Tests if the current instance of CRNum is a fixed length value or not. Typically a fixed length value is anything from NUM_LENGTH_EM to NUM_LENGTH_PC. See the definition of CRNumType to see what we mean.
Returns TRUE if the instance of CRNum is a fixed length number, FALSE otherwise.
