A function that is built into an application and can be accessed by end-users.A function is similar to a normal procedure but the main purpose of the function is to accept a certain input from the user and return a value which is passed on to the main program to finish the execution. There are two types of functions, the built-in functions (or internal functions) and the functions created by the programmers. he general format of a function isFunctionName (arguments) The arguments are values that are passed on to the function.Built -in function are classified under following categories * Math Functions * Conversion Functions * String Functions * Date and Time Functions * Array Functions * Misc. FunctionsMath Functions * Abs(vNumber) - Returns the absolute value of a specified number * Atn(vNumber) - Returns the arctangent of a specified number * Cos(vNumber) - Returns the cosine of a specified number (angle) * Exp(vPower) - Returns e raised to a power * Hex(vNumber) - Returns the hexadecimal value of a specified number * Int(vNumber) - Returns the integer part of a specified number * Fix(vNumber) - Returns the integer part of a specified number * Log(vNumber) - Returns the natural logarithm of a specified number * Oct(vNumber) - Returns the octal value of a specified number * Rnd() - Returns a random number less than 1 but greater or equal to 0 * Sgn(vNumber) - Returns an integer that indicates the sign of a specified number * Sin(vNumber) - Returns the sine of a specified number (angle) * Sqr(vNumber) - Returns the square root of a specified number * Tan(vNumber) - Returns the tangent of a specified number (angle) Conversion Functions * CBool(vVariant) - Converts an expression to a variant of subtype Boolean * CByte(vVariant) - Converts an expression to a variant of subtype Byte * CCur(vVariant) - Converts an expression to a variant of subtype Currency * CDate(vVariant) - Converts a valid date and time expression to the variant of subtype Date * CDbl(vVariant) - Converts an expression to a variant of subtype Double * CInt(vVariant) - Converts an expression to a variant of subtype Integer * CLng(vVariant) - Converts an expression to a variant of subtype Long * CSng(vVariant) - Converts an expression to a variant of subtype Single * CStr(vVariant) - Converts an expression to a variant of subtype StringString Functions * InStr(sString, sSubString) - Returns the position of the first occurrence of one string within another. The search begins at the first character of the string * InStrRev(sString, sSubString) - Returns the position of the first occurrence of one string within another. The search begins at the last character of the string * LCase(sString) - Converts a specified string to lowercase * Left(sString, iLen) - Returns a specified number of characters from the left side of a string * Len(sString) - Returns the number of characters in a string * LTrim(sString) - Removes spaces on the left side of a string * RTrim(sString) - Removes spaces on the right side of a string * Trim(sString) - Removes spaces on both the left and the right side of a string * Mid(sString, iStart, iLen) - Returns a specified number of characters from a string * Replace(sString, sOld, sNew) - Replaces a specified part of a string with another string a specified number of times * Right(sString) - Returns a specified number of characters from the right side of a string * Space(iLen) - Returns a string that consists of a specified number of spaces * StrComp(sString1, sString2) - Compares two strings and returns a value that represents the result of the comparison * String(iLen, sChar, iLen) - Returns a string that contains a repeating character of a specified length * StrReverse(sString) - Reverses a string * UCase(sString) - Converts a specified string to uppercase * Asc(sString) - Converts the first letter in a string to ANSI code * Chr(iInteger) - Converts the specified ANSI code to a character Date and Time Functions * CDate(vVariant) - Converts a valid date and time expression to the variant of subtype Date * Date() - Returns the current system date * DateAdd(sType, iInterval, tDate) - Returns a date to which a specified time interval has been added * DateDiff(tDate1, tDate2) - Returns the number of intervals between two dates * DatePart(sType, tDate) - Returns the specified part of a given date * DateSerial(iYear, iMonth, iDate) - Returns the date for a specified year, month, and day * DateValue(vVariant) - Returns a date * Day(tDate) - Returns a number that represents the day of the month (between 1 and 31, inclusive) * FormatDateTime(tDate, iType) - Returns an expression formatted as a date or time * Hour(tDate) - Returns a number that represents the hour of the day (between 0 and 23, inclusive) * IsDate(vVariant) - Returns a Boolean value that indicates if the evaluated expression can be converted to a date * Minute(tDate) - Returns a number that represents the minute of the hour (between 0 and 59, inclusive) * Month(tDate) - Returns a number that represents the month of the year (between 1 and 12, inclusive) * MonthName(iMonth) - Returns the name of a specified month * Now() - Returns the current system date and time * Second(tDate0 - Returns a number that represents the second of the minute (between 0 and 59, inclusive) * Time() - Returns the current system time * Timer() - Returns the number of seconds since 12:00 AM * TimeSerial(iHour, iMinute, iSecond) - Returns the time for a specific hour, minute, and second * TimeValue(tDate) Returns a time * Weekday(tDate) - Returns a number that represents the day of the week (between 1 and 7, inclusive) * WeekdayName(iWeekDay) - Returns the weekday name of a specified day of the week * Year(tDate) - Returns a number that represents the yearArray Functions * Array(vArg1, vArg2, ...) - Returns a variant containing an array * IsArray(vVariant) - Returns a Boolean value that indicates whether a specified variable is an array * Join(aArray) - Returns a string that consists of a number of substrings in an array * LBound(aArray) - Returns the smallest subscript for the indicated dimension of an array * Split(sString, sDelimiter) - Returns a zero-based, one-dimensional array that contains a specified number of substrings * UBound(aArray) - Returns the largest subscript for the indicated dimension of an arrayMisc.
