round is used to round off the given digit which can be in float or double. If decimal value is from ”.1 to .5″, it returns integer value less than the argument. Second, rounding is never defined in terms of IEEE floating point behavior, but deliberately defined in somewhat arbitrary ways to suit the situation. For instance, say you round 37.777779 to 37.78, but the nearest representable number is 37.781. It returns the nearest integral value to provided parameter in round function, with halfway cases rounded away from zero. By using our site, you 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. Instead of round(), std::round() can also be used . Float is a datatype which is used to represent the floating point numbers. 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:. How to round off a floatig point value to two places. 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. For example, if user has provided 23.43 as input, then the program will output its nearest integer value that will be 23 How to round off a floatig point value to two places. 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).

It has 6 decimal digits of precision. acknowledge that you have read and understood our By using our site, you Because we're dealing with money, rounding things the "wrong" way, as defined by various laws or contracts, could actually qualify as fraud.
For example, 5.567 should become 5.57 and 5.534 should become 5.53. Convert float value to an int or Round float value.

Don’t stop learning now. 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 . In this tutorial, we will learn about round function in C programming language. 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. round( ) function in C returns the nearest integer value of the float/double/long double argument passed to this function.
