In the C Programming Language, the floor function returns the largest integer that is smaller than or equal to x (ie: rounds downs the nearest integer).
C floor() function - Find Integer Syntax: double floor(double x) The floor() function is used to calculate the largest integer that is less than or equal to x. Parameters: Return value from floor() function Returns the floating-point result as a double value. Example: floor() function T...
Following is the basic C library example to see the demonstration offloor()function. Open Compiler #include<stdio.h>#include<math.h>intmain(){floatval1,val2,val3,val4;val1=1.6;val2=1.2;val3=2.8;val4=2.3;printf("Value1 = %.1lf\n",floor(val1));printf("Value2 = %.1lf\n",floo...
The floor() function is defined in the <math.h> header file.Tip: To round a number UP to the nearest integer, look at the ceil() function.Tip: To round a number to the nearest integer in either direction, look at the round() function....
#include<iostream>#include<cmath>intmain(){double num=3.4;double result=ceil(num);std::cout<<"向上取整结果: "<<result<<std::endl;return0;} 输出结果: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 向上取整结果:4 在示例中,我们使用了 ceil 函数将浮点数 3.4 向上取整为最接近的整数 4。
C 库函数 double floor(double x) 返回小于或等于 x 的最大的整数值。floor() 是C 标准库 <math.h> 中的一个函数,用于返回小于或等于传入参数的最大整数值(即向负无穷取整)。这个函数在数学和工程中常被用于向下取整。声明下面是 floor() 函数的声明。

This function returns an integer value not greater than its argument, i.e., a scalar or vector number without decimal places, rounded down, e.g., the floor of 1.97f returns 1; why? Because this function subtracts the decimals of a number from its total. Its syntax is as follows: ...
FLOOR(number, significance) The FLOOR function syntax has the following arguments: NumberRequired. The numeric value you want to round. SignificanceRequired. The multiple to which you want to round. Remarks If either argument is nonnumeric, FLOOR returns the #VALUE! error value. ...
