Reads a Number from file and returns it. The function will read as much of the text as can be interpreted as a number . It will stop at any character that cannot be construed as being part of a number . If the line begins with a character that is not part of an integer value, the results are unpredictable.
Alternatives for reading data from text files include the functions readLinesFromFile() and readSimpleDataFile(), the TextFile design , and the ADO.NET library.
