Floor function floor (x), sometimes it is also written as floor (x), its function is "rounding", or "rounded down", that is, take the largest integer not greater than X (and "Rounding", the next rounding is directly remove the decimal part), such as:

Floor returns the largest integer not greater thanRound is the calculation of 4 5 in, when it is greater than its integerRound method, which means "rounding", the algorithm is Math.floor (x+0.5), the original number is added 0.5 and then rounded

Ceil Function The Ceil function is used to evaluate the smallest integer not less than the given real number.Ceil (2) = Ceil (1.2) = CEI (1.5) = 2.00 To use this function, you must include the header file . The return

It is troublesome to perform Integer Optimization in Java, especially rounding and rounding. The following are three integer operations (including truncation, rounding, and rounding) based on some answers on the Internet, which are similar to

ABS   Prototype: extern int ABS (int x ); Usage: # include Function: calculates the absolute value of integer x. Description: calculation | x |. If X is not negative, X is returned. Otherwise,-X is returned. Example: // Abs. c # Include # Include

The interpolation method can be used for image enlargement. One simple interpolation method is linear interpolation, which is very effective even though simple. Linear interpolationThe so-called linear interpolation means that there is a set of

When processing some data, we hope to use the "Rounding" method, but C # uses the "four homes, six homes, five into two" method, as shown in the following example, the result is obtained using "four homes, six homes, and five into two: Code
