The floor() function rounds a number DOWN to the nearest integer.The floor() function is defined in the <cmath> 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...
Syntax of floor() function: floor(x); Parameter(s) x– is the number whose value to round up. Return value double– it returns double type value that is the rounded up value of the given number. Sample Input and Output Input: float x = 2.3; Function call: floor(x); Output: 2 Inp...
Edit & run on cpp.sh Sep 29, 2016 at 2:07am Nico(251) Are you sure you had sufficient digits? When I tried it with 1.12345678, I got exactly the output I would expect. So I think maybe you should check your input or rebuild your program, as this source code seems correct. ...

In a C program, unless you're using the <tgmath.h> macro to call this function, floor always takes and returns a double.If you use the <tgmath.h> floor() macro, the type of the argument determines which version of the function is selected. See Type-generic math for details....
在本教程中,我们将借助示例了解 C++ floor() 函数。 C++ 中的floor()函数返回小于或等于给定参数的最大可能整数值。 它在cmath头文件中定义。 示例 #include<iostream>#include<cmath>usingnamespacestd;intmain(){// get the largest possible integer less than or equal to 68.95cout<<floor(68.95);return...
The largest representable floating-point values are exact integers in all standard floating-point formats, so this function never overflows on its own; however the result may overflow any integer type (includingstd::intmax_t), when stored in an integer variable. ...
