How would you round a value from 4.77 to 5.0 in C?
Solution; If the number to be rounded off is greater than 5 then the preceding digit is increased by one if the number to be rounded off is less than 5 then the preceding digit is kept the same. According to these rules, we can round off the number. 4.77 round off to nearest 100 is 5.00.

What is double in C?
A double is a data type in C language that stores high-precision floating-point data or numbers in computer memory. It is called double data type because it can hold the double size of data compared to the float data type. A double has 8 bytes, which is equal to 64 bits in size.
What is divided in C?
Division in C In C language, when we divide two integers, we get an integer result, e.g., 5/2 evaluates to 2. As a general rule integer/integer = integer, float/integer = float and integer/float = float.
How does C handle division?
Integer division yields an integer result. For example, the expression 7 / 4 evaluates to 1 and the expression 17 / 5 evaluates to 3. C provides the remainder operator, %, which yields the remainder after integer division.
How do you round to the nearest 10?
Key Facts and Summary
- Rounding off to the nearest 10 means that we wish to round off the last two digits of a number, i.e. up to the tens place of a number.
- If that digit is 0, 1, 2, 3, or 4, you will round down to the previous tens. ( Round down)
- If that digit is 5, 6, 7, 8, or 9, you will round up to the next ten. (
How do you round to the nearest hundredth in C#?
“c# math round up decimal to hundredths” Code Answer’s
