General functionsFollowing are brief descriptions of the functions that can be used with all data types. For more detailed information about a specific function (such as usage and syntax), click the function name.
ifThis function uses three expressions as input. If the first expression evaluates to true, the second expression is evaluated and used as the result (the third expression is not evaluated). If the first expression evaluates to false, then the third expression is evaluated and used as the result (the second expression is not evaluated). The first expression must be type boolean; the second and third expressions must be the same type. Use the following syntax: if (bool_expr, expr2, expr3)
maxThis function returns the largest value from a list of expressions; it does not, however, identify the expression that contained the value. Use the following syntax: max (expr {, expr }0+) where expr is an expression of any supported data type. For example, if x = 8, y = 13, and z = 28, the following expression returns the value 53. max (x +2, y, z, 53, 1, 17.4)
minThis function returns the smallest value from a list of expressions; however, it does not identify the expression that contained the value. Use the following syntax: min (expr {, expr }0+) where expr is an expression of any supported data type. For example, if x = 8, y = 13, and z = 28, the following expression returns the value 1. min (x +2, y, z, 2*z, 53, 1, 17.4)
sizeofThis function computes the size of an array, returning the highest subscript used for an element of the given array. For example, if you specify entries for locations 5, 7, 8, 15, and 25 in an array, sizeof returns the number 25, even though only 5 locations in the array have non-defaulted entries. (Normally, you fill array locations in order.) Use the following syntax: sizeof (array_id) where array_id is the name of the array.
