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...

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....
Floor function Sep 29, 2016 at 1:46am my2jlw3s(2) Hey guys, trying to write a program using the floor function that outputs a whole integer, rounded to the tenths, rounded to the hundredths, and finally rounded to the thousandths. This in the code I have currently, but its outputting...

If you use the <tgmath.h>floor()macro, the type of the argument determines which version of the function is selected. SeeType-generic mathfor details. By default, this function's global state is scoped to the application. To change this behavior, seeGlobal state in the CRT. ...
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. ...
