Bookshelf v8.1/8.2: Using Siebel eScript Methods Instead of Clib Methods

Table 123 lists each Clib method that has an equivalent method in Siebel eScript. These methods are redundant because their functionality already exists in Siebel eScript. Where possible, you must use the Siebel eScript method instead of the equivalent Clib method. In some situations the Clib method is preferred and is more consistent in a section of script. For example, when working with a string routine that expects a null string.

Table 123. Siebel eScript You Can Use Instead of Clib Methods
Siebel eScript Method	Clib Method	Description
Get Absolute Value Method	abs	Calculates absolute value.
Get Arc Cosine Method	acos	Calculates the arc cosine.
Get Arcsine Method	asin	Calculates the arc sine.
Get Arctangent Method	atan	Calculates the arc tangent.
Get Arctangent 2 Method	atan2	Calculates the arc tangent of a fraction.
Convert String to Floating-Point Number Method	atof	Converts a string to a floating-point number.
Convert String to Integer Method	atoi	Converts a string to an integer.
Automatic conversion	atol	Converts a string to a long integer.
Get Ceiling Method	ceil	Rounds a number up to the nearest integer.
Get Cosine Method	cos	Calculates the cosine.
Get Exponential Method	exp	Calculates the exponential function.
Math absolute	fabs	Calculates the absolute value of a floating-point number.
Get Floor Method	floor	Rounds a number down to the nearest integer.
% operator, modulo	fmod	Calculates the remainder.
Math absolute	labs	Returns the absolute value of a long.
Get Logarithm Method	log	Calculates the natural logarithm.
Get Maximum Method	max	Returns the largest of one or more values.
Get Minimum Method	min	Returns the smallest of one or more values.
Raise Power Method	pow	Calculates x to the power of y.
Get Sine Method	sin	Calculates the sine.
Get Square Root Method	sqrt	Calculates the square root.
+ operator	strcat	Appends one string to another.
== operator	strcmp	Compares two strings.
= operator	strcpy	Copies a string.
Get String Length Method	strlen	Gets the length of a string.
Change String to Lowercase Method	strlwr	Converts a string to lowercase.
Automatic conversion	strtod	Converts a string to decimal.
Automatic conversion	strtol	Converts a string to long.
Change String to Uppercase Method	strupr	Converts a string to uppercase.
Get Tangent Method	tan	Calculates the tangent.
string.toLowerCase	tolower	Converts a character to lowercase.
string.toUpperCase	toupper	Converts a character to uppercase.

The phrase automatic conversion in the Siebel eScript Method column means that Siebel eScript implicitly performs a conversion. For example, when comparing Siebel eScript to the atol Clib method, if the variable that will hold the converted string is of type Number, then Siebel eScript implicitly converts the string from a string to a long integer.
