Informix DataBlade API Programmer's Manual DataBlade API Function Descriptions

The mi_type_precision() function obtains the precision of a data type from its type descriptor.

mi_integer mi_type_precision(type_desc)

MI_TYPE_DESC *type_desc;

type_desc

is a pointer to the type descriptor from which mi_type_precision() obtains the precision.

Valid in Client LIBMI Application?	Valid in User-Defined Routine?
Yes	Yes

The mi_type_precision() function obtains the data type precision from the type descriptor that type_desc references. The precision is an attribute of the data type that represents the total number of digits the data type can hold, as follows.

If you call mi_type_precision() on some other data type, the function returns zero (0).

See the descriptions of the following functions: mi_type_align(), mi_type_byvalue(), mi_type_element_typedesc(), mi_type_full_name(), mi_type_length(), mi_type_maxlength(), mi_type_owner(), mi_type_qualifier(), mi_type_scale(), mi_type_typedesc(), and mi_type_typename().

For information on type-descriptor accessor functions, see Type Descriptors. For information on precision and scale, see Chapter 3, Using Numeric Data Types.
