TuxSetFloat Function

Action

Sets the value of a specified floating-point field within a typed buffer. This function can be used to manipulate any of the following predefined buffer types:

FML, FML32

Include file

TUXEDO.bdh

Syntax

TuxSetFloat(in hBuffer  : number,
            in nFieldId : number,
            in fValue   : float,
            in nIndex   : number optional): boolean;

Return value

true if successful
false otherwise

Parameter	Description
hBuffer	Typed buffer allocated with TuxGetBuffer or Tux_tpalloc.
nFieldId	Identifier specifying a field of the typed buffer.
fValue	Floating-point value to copy to the typed buffer.
nIndex	Array index (optional). This parameter has to be passed to the function if the field identifier specifies an array.

Example

const
  ID_NUMBERS :=  8;
  ID_PRODUCT := 16; 

dcltrans
  transaction TMain
  var
  hBuffer, olen : number;
  fResult       : float;
  
  begin
  Tux_tpbegin(30, 0); 

    // allocate buffer
    TuxGetBuffer(hBuffer, "FML", NULL, 1024); 

    // store two floating-point values in buffer
    TuxSetFloat(hBuffer, ID_NUMBERS, 807.33, 1);
    TuxSetFloat(hBuffer, ID_NUMBERS, 23.09, 2); 

    // multiply floating-point values
    Tux_tpcall("MULTIPLY", hBuffer, 0, hBuffer, olen, TPNOFLAGS);

    // retrieve product
    fResult := TuxGetFloat(hBuffer, ID_PRODUCT);
    Tux_tpcommit(0);
  end TMain;
