ceil in c

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

Use the floor function. Floor (x) returns the largest integer less than or equal to X.For example, floor (10.5) = 10 floor (-10.5) =-11 Use the ceil function. Ceil (x) returns the smallest integer greater than X.For example, Ceil (10.5) = 11 Ceil (-

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

Take a direct look at the show: # Psy Shell v0.3.3 (PHP 5.5.30-cli) by Justin hileman>>> ceil ( -0.5) = -0.0>>> max ( -0.0, 0) = 0.0 >>> Max (Ceil ( -0.5), 0) = 0.0 In the above demo, the Ceil function returns a 0.0 when -0.0,max passes the

A small BUG in maxmin function (PHP) is shown in the following figure: # Psy Shell v0.3.3 (PHP 5.5.30 — cli) by Justin Hileman>>> ceil(-0.5)=> -0.0>>> max(-0.0, 0)=> 0.0>>> max(ceil(-0.5), 0)=> -0.0 In the above demonstration, the ceil function

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
