In our first example, we will create a program that takes decimal input and pass it to the floor function. Initially, open a blank notepad and give it a name of your choice. Add a .cpp extension because we will be using this notepad file for creating a C program. We have named our ...
intmain() { // using ceil function which return // floor of input value cout<<" Ceil is : "<<ceil(2.3)<<endl; cout<<" Ceil is : "<<ceil(-2.3)<<endl; return0; } Ceilis:3 Ceilis:-2 注:本文由VeryToolz翻译自Ceil and Floor functions in C++,非经特殊声明,文中代码和图片版权归...
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....
Tip:To round a number UP to the nearest integer, look at theceil()function. Tip:To round a number to the nearest integer in either direction, look at theround()function. Syntax One of the following: floor(doublenumber); floor(floatnumber); ...

The floor() Function In C++, to obtain the floor of a number, use the following function: double floor(double Value); Thefloor()function takes the considered value as the argument and returns the integer that is less than or equal to Value. Here is an example: ...
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. ...
