For example, 5.567 should become 5.57 and 5.534 should become 5.53Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above.Attention reader! In the C Programming Language, the round() function returns the nearest integer value of the float/double/argument passed to this function. 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:. In this tutorial, we will learn about round function in C programming language. Don’t stop learning now. By using our site, you Syntax. Instead of round(), std::round() can also be used . The library described in clause 7 of ISO/IEC 9899:1990 and clause 7 of ISO/IEC 9899/Amd.1:1995 is hereinafter called the Standard C Library. acknowledge that you have read and understood our

we can convert very easily, For Converting floating point value, add 0.5 and convert to integer we can get correct answer, floating_point_value + 0.5 and Convert to int . We use cookies to ensure you have the best browsing experience on our website. For instance, say you round 37.777779 to 37.78, but the nearest representable number is 37.781. How to round off a floatig point value to two places. Float is a datatype which is used to represent the floating point numbers. The syntax of the round() function in C language round( ) function in C returns the nearest integer value of the float/double/long double argument passed to this function. Convert float value to an int or Round float value. Because we're dealing with money, rounding things the "wrong" way, as defined by various laws or contracts, could actually qualify as fraud. How to round off a floatig point value to two places. 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. Don’t stop learning now. First Method:- Using Float precision

For example, 5.567 should become 5.57 and 5.534 should become 5.53. It returns the nearest integral value to provided parameter in round function, with halfway cases rounded away from zero. 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. 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). However, you can "round" a float by using a format string function. Declaration. If decimal value is from ”.1 to .5″, it returns integer value less than the argument. For example, if user has provided 23.43 as input, then the program will output its nearest integer value that will be 23 Second, rounding is never defined in terms of IEEE floating point behavior, but deliberately defined in somewhat arbitrary ways to suit the situation.
