Second, rounding is never defined in terms of IEEE floating point behavior, but deliberately defined in somewhat arbitrary ways to suit the situation. acknowledge that you have read and understood our We use cookies to ensure you have the best browsing experience on our website. It returns the nearest integral value to provided parameter in round function, with halfway cases rounded away from zero. Here, in the above program we have just calculated the nearest integral value of given float or double value.Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above.Attention reader!

C Program to Round off any Number to its Nearest Integer - In this tutorial, we will learn about how to create a program in C that will ask from user to enter any number (any real or floating-point number) to round it off to its nearest integer.
There isn't a way to round a float to another float because the rounded float may not be representable (a limitation of floating-point numbers). The C++03 standard relies on the C90 standard for what the standard calls the Standard C Library which is covered in the draft C++03 standard (closest publicly available draft standard to C++03 is N1804) section 1.2 Normative references:. Syntax. It is a 32-bit IEEE 754 single precision floating point number ( 1-bit for the sign, 8-bit for exponent, 23*-bit for the value. By using our site, you
For example, if user has provided 23.43 as input, then the program will output its nearest integer value that will be 23 acknowledge that you have read and understood our Don’t stop learning now.

The syntax of the round() function in C language Convert float value to an int or Round float value. round( ) function in C returns the nearest integer value of the float/double/long double argument passed to this function. Declaration.
Because we're dealing with money, rounding things the "wrong" way, as defined by various laws or contracts, could actually qualify as fraud. If decimal value is from ”.1 to .5″, it returns integer value less than the argument. Explanation: here,
