Release 10.1A: OpenEdge Development:
Progress 4GL Reference

GET-FLOAT function

Returns the 4-byte floating-point value at the specified memory location as a DECIMAL.

Syntax

GET-FLOAT ( source , position )

source

A function or variable that returns a RAW or MEMPTR value. If source is the Unknown value (?), GET-FLOAT returns the Unknown value (?).

position

An integer value greater than 0 that indicates the byte position where you want to find the information. If position is greater than the length of source, Progress returns the Unknown value (?). If position is less than 1, Progress generates a run-time error.

Examples

For examples of how to use the GET-FLOAT function, see the GET-BYTE function reference entry.

Notes

This function supports byte-swapping only if source is a MEMPTR data type. The function will first examine the byte-order setting of the MEMPTR and then swap the bytes appropriately before interpreting them. Progress does not swap the bytes in the MEMPTR’s memory, but does the byte-swap as it creates the return value.
For more information on using the MEMPTR data type, see OpenEdge Development: Programming Interfaces .
For more information on using the RAW data type, see OpenEdge Development: Programming Interfaces .
