Str()
Str()
Convert a numeric expression to a character string.
Syntax
Str( <nNumber>, [<nLength>], [<nDecimals>] ) --> cNumber
Arguments
<nNumber> is the numeric expression to be converted to a character string.
<nLength> is the length of the character string to return, including decimal digits, decimal point, and sign.
<nDecimals> is the number of decimal places to return.
Returns
Str() returns <nNumber> formatted as a character string. If the optional length and decimal arguments are not specified, Str() returns the character string according to the following rules:
Results of Str() with No Optional Arguments
Expression Return Value Length
------------------------ -----------------------------------
Field Variable Field length plus decimals
Expressions/constants Minimum of 10 digits plus decimals
Val() Minimum of 3 digits
Month()/Day() 3 digits
Year() 5 digits
RecNo() 7 digits
Description
Str() is a numeric conversion function that converts numeric values to character strings. It is commonly used to concatenate numeric values to character strings. Str() has applications displaying numbers, creating codes such as part numbers from numeric values, and creating index keys that combine numeric and character data.
Str() is like Transform(), which formats numeric values as character strings using a mask instead of length and decimal specifications.
The inverse of Str() is Val(), which converts character numbers to numerics.
* If <nLength> is less than the number of whole number digits in <nNumber>, Str() returns asterisks instead of the number.
* If <nLength> is less than the number of decimal digits required for the decimal portion of the returned string, Harbour rounds the number to the available number of decimal places.
* If <nLength> is specified but <nDecimals> is omitted (no decimal places), the return value is rounded to an integer.
Examples
? Str( 10, 6, 2 ) // " 10.00"
? Str( -10, 8, 2 ) // " -10.00"

INT()
Return the integer port of a numeric value.
Syntax
INT( <nNumber> ) --> <nIntNumber>
Arguments
<nNumber> Any numeric value.
Returns
<nIntNumber> The integer portion of the numeric value.
Description
This function converts a numeric expression to an integer. All decimal digits are truncated. This function does not round a value upward or downward; it merely truncates a number at the decimal point.
Examples
SET DECIMAL TO 5
? INT( 632512.62541 )
? INT( 845414111.91440 )

Main difference is allowing file(s) and folder(s) selection together.
Another difference is implementing of <lNoChangeDir> parameter. Unlike GetFile(), GetDIRList() uses this value for allowing change directory ability to user.
Furthermore sorting grid columns by three (not two) ways, GetVolumLabel(), List2Arry() and Arry2List() functions may be useful.
Also, test program ( TestGDL.prg ) may be a sample for .fmg based application.
