ingres_field_precision — Get the precision of a field

### Description

int ingres_field_precision ( resource `$result` , int `$index` )

ingres_field_precision() returns the precision of a field. This value is used only for decimal, float, and money SQL data types. For detailed information, see the Ingres OpenAPI User Guide, Appendix "Data Types" in the Ingres documentation.

> Note: Related Configurations
> See ingres.array_index_start in Runtime Configuration

### Parameters

`result`

  The query result identifier

`index`

  `index` is the field whose precision will be retrieved.

  The possible values of `index` depend upon the value of ingres.array_index_start. If ingres.array_index_start is 1 (the default) then `index` must be between 1 and the value returned by ingres_num_fields(). If ingres.array_index_start is 0 then `index` must be between 0 and ingres_num_fields() - 1.

### Return Values

Returns the field precision as an integer
