ABS (x ):Basic syntax and crystal syntax.Parameter: X is the number or currency in which you want to return the absolute value.Return Value: Numeric ValueOperation: ABS (x) returns the absolute value of X.Example:ABS (1, 1.50)1.50 is returned. ABS (-1, 1.50)1.50 is returned. ABS (10-7)3 is returned. ABS (7-10)3 is returned. Rem basic syntax:If ABS (37-{file.

negative integer, 0 or a positive integer, because this object corresponds to less than, equal to, or greater than the specified object. If the type of the specified object cannot be compared with this object, an exception is thrownClassCastException. In the following description, the symbol SGN (expression) represents the Signum function in mathematics, which corresponds to return 1, 0, and 1, depending on the value of the expression as n

Half plane intersection template O (N ^ 2) in http://www.cnblogs.com/wuyiqi/archive/2012/03/30/2426175.html Question: Judge the sum of the shortest cut marks of the convex polygon required to be cut out on a square. There are only eight sides in total, and the data size is small. The time limit is 10 s. The order of brute force enumeration and cutting is calculated. This is my first contact with plane cutting. It can be called a virgin cutting. View code # Include # Include # Include

type of problem the perceptron applies to, so I'm here for an example: in two dimensions, the perceptron is equivalent to a flat line on the plane, thus dividing the plane into two halves; in three-dimensional situations, the perceptron is equivalent to a knife in the space of a chopper, thus dividing the space into two categories. These two sentences are equivalent to the following sentence in their scope of application: The perceptual machine corresponds to the input space (characteristic spa

Mathematical functions simplify programming for mathematical and geometric processes. When you use these functions, remember that some functions can be obtained from other functions. radians = degrees * pi/180 degrees = radians * 180/PI PI = 3.1415926535897932 Natural logarithm: E = 2.718322 Sin (a) = A/C Cos (a) = b/c Tan (a) = A/b Sec (a) = 1/cos (a) Cosec (a) = 1/sin (a) Cotan (a) = 1/tan (a) Arcsin (x) = Atn (X/sqr (-x*x+1)) Arccos (x) = Atn (-x/sqr (-x*x+1)) + 2*atn (1) ARCSEC (x) = Atn (X/
