# PX\_get\_data\_double(3)

Get double data field

## NAME

PX\_get\_data\_double — Get double data field

## SYNOPSIS

\#include \<paradox.h\>

int PX\_get\_data\_double(pxdoc\_t \*pxdoc, char \*data, int len, double \*value)

## DESCRIPTION

Converts a data field as it stored in the database file into  a double for the host architecture. You should use this function  instead of accessing the data directly.

**data** points to the start of the data field in the  record. It must be calculated by summing up all field length before  the field to operate on and add it to the base pointer of the  record.

**Note:**

**This function is deprecated and obsolete if**  **[PX\_retrieve\_record(3)](/PX_retrieve_record/3.md) is used.**

## RETURN VALUE

**Returns 0 if the value is NULL, -1 in case of an error and 1**  **otherwise.**
