Description

The WriteFloat method writes a floating-point value to a binary file.

Declaration

aqBinaryFileObj.WriteFloat()

aqBinaryFileObj	An expression, variable or parameter that specifies a reference to an aqBinaryFile object
Result	Double

Applies To

The method is applied to the following object:

aqBinaryFile

Result Value

The floating-point value to write to a file.

Remarks

On success, the cursor position is shifted by the length of the written data.
To use this method, you should open the needed file with the faWrite or faReadWrite access permission. See the description of the OpenBinaryFile method.

Example

The code below opens a file for reading, posts its data to the test log in different formats (binary, boolean, and so on) and then closes the file.

JavaScript, JScript

function ReadingDataFromBinaryFile()
{
Path = "C:\\MyFiles\\FileName.txt";

// Creates a new file and opens it for writing in binary mode
myFile = aqFile.OpenBinaryFile(Path, aqFile.faWrite, true);

// Writes data to the file
myFile.WriteBool(false);
myFile.WriteCurrency(3000000000);
myFile.WriteDate(aqDateTime.Today());
myFile.WriteFloat(1543.514)
myFile.WriteInt(58942);
myFile.WriteString("Hello!");

// Closes the file
myFile.Close();

// Opens the file for reading
myFile = aqFile.OpenBinaryFile(Path, aqFile.faRead);

// Reads data from the file in different formats
Log.Message("The bolean is: "+ myFile.ReadBool());
Log.Message("The currency is: "+ myFile.ReadCurrency());
Log.Message("The date is: " + myFile.ReadDate());
Log.Message("The float number is: " + myFile.ReadFloat());
Log.Message("The integer number is: "+ myFile.ReadInt());
Log.Message("The string is: "+ myFile.ReadString(6));

// Closes the file
myFile.Close();
}
