Stores the 4-byte floating-point value of a DECIMAL expression at the specified memory location.
Syntax
PUT-FLOAT ( destination , position ) = expression
destination
A variable of type RAW or MEMPTR. If destination is the Unknown value (?), it remains the Unknown value (?). If destination is a MEMPTR and has not had its region allocated (by a SET-SIZE statement or by a Windows dynamic link library (DLL) or UNIX shared library routine), the AVM generates a run-time error.
position
An integer value greater than 0 that indicates the byte position where the AVM stores expression. If position is less than 1, the AVM generates a run-time error.
For a RAW destination, if position is greater than the length of destination, the AVM increases the length of destination to position plus the remaining bytes needed to store expression. The gap between the original destination length and position is padded with null bytes.
For a MEMPTR destination, if position is greater than the length of destination or does not leave sufficient room to store expression, the AVM generates a run-time error.
expression
The DECIMAL value of a constant, field, variable, function, or expression.
Example
For examples of how to use the PUT-FLOAT statement, see the PUT-BYTE statement reference entry.
Notes
This statement supports byte-swapping only if destination is a MEMPTR data type. The statement will first examine the byte-order setting of the MEMPTR and then swap the bytes appropriately while putting the data into the MEMPTR memory.
