Chr CInt CLng Functions In Qtp

What is Chr,CInt,CLng Function :
 Returns the character associated with the specified ANSI character code.

Chr(charcode)
The charcode argument is a number that identifies a character.

Remarks

Numbers from 0 to 31 are the same as standard, nonprintable ASCII codes. For example, Chr(10) returns a linefeed character.
The following example uses the Chr function to return the character associated with the specified character code:
Dim MyChar MyChar = Chr(65)   ' Returns A. MyChar = Chr(97) 
' Returns a. MyChar = Chr(62) 
' Returns >. MyChar = Chr(37)   ' Returns %.
Note   The ChrB function is used with byte data contained in a string. Instead of returning a character, which may be one or two bytes, ChrB always returns a single byte. ChrW is provided for 32-bit platforms that use Unicode characters. Its argument is a Unicode (wide) character code, thereby avoiding the conversion from ANSI to Unicode.
Returns an expression that has been converted to a Variant of subtype Integer.
CInt(expression)
The expression argument is any valid expression.

Remarks

In general, you can document your code using the subtype conversion functions to show that the result of some operation should be expressed as a particular data type rather than the default data type. For example, use CInt or CLng to force integer arithmetic in cases where currency, single-precision, or double-precision arithmetic normally would occur.
Use the CInt function to provide internationally aware conversions from any other data type to an Integer subtype. For example, different decimal separators are properly recognized depending on the locale setting of your system, as are different thousand separators.
If expression lies outside the acceptable range for the Integer subtype, an error occurs.
The following example uses the CInt function to convert a value to an Integer:
Dim MyDouble, MyInt MyDouble = 2345.5678     
' MyDouble is a Double. MyInt = CInt(MyDouble)

' MyInt contains 2346.
Note   CInt differs from the Fix and Int functions, which truncate, rather than round, the fractional part of a number. When the fractional part is exactly 0.5, the CInt function always rounds it to the nearest even number. For example, 0.5 rounds to 0, and 1.5 rounds to 2.

Returns an expression that has been converted to a Variant of subtype Long.
CLng(expression)
The expression argument is any valid expression.

Remarks

In general, you can document your code using the subtype conversion functions to show that the result of some operation should be expressed as a particular data type rather than the default data type. For example, use CInt or CLng to force integer arithmetic in cases where currency, single-precision, or double-precision arithmetic normally would occur.
Use the CLng function to provide internationally aware conversions from any other data type to a Long subtype. For example, different decimal separators are properly recognized depending on the locale setting of your system, as are different thousand separators.
If expression lies outside the acceptable range for the Long subtype, an error occurs.
The following example uses the CLng function to convert a value to a Long:
Dim MyVal1, MyVal2, MyLong1, MyLong2 MyVal1 = 25427.45: 
MyVal2 = 25427.55   

' MyVal1, MyVal2 are Doubles. MyLong1 = CLng(MyVal1)   
' MyLong1 contains 25427. MyLong2 = CLng(MyVal2)
 ' MyLong2 contains 25428.
Note   CLng differs from the Fix and Int functions, which truncate, rather than round, the fractional part of a number. When the fractional part is exactly 0.5, the CLng function always rounds it to the nearest even number. For example, 0.5 rounds to 0, and 1.5 rounds to 2.
