These built in operations, such as, square root, absolute value, and tangent, are called intrinsic functions . The natural logarithm of X is such an intrinsic function. The argument of a function is the input value to that function and can be a constant, a variable, or an expression. An intrinsic function and its argument represent a value . The type of value returned by a function is determined by the function.
Some intrinsic functions are generic meaning that they return the same type as their input argument.
Table 1 lists some commonly used intrinsic functions. The REAL function can help avoid mixed mode arithmetic expressions by explicitly converting variable types. For example, when computing the average of a set of REAL values it is necessary to divide the real sum of the values by the number of values. The values for the x and y coordinates for point A and point B are assigned. Code Part of the code is done for you.
