Why is there a difference between integer division and float division?
The division operator / means integer division if there is an integer on both sides of it. If one or two sides has a floating point number, then it means floating point division. The result of integer division is always an integer. The remainder after integer division is simply dropped, no matter how big it is.
When an integer is divided by an integer using the operator the result will be a float?
Dividing an integer by an integer gives an integer result. 1/2 yields 0; assigning this result to a floating-point variable gives 0.0. To get a floating-point result, at least one of the operands must be a floating-point type.
What happens when you divide an integer in C?
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. The remainder operator is an integer operator that can be used only with integer operands.
Can an int function return a float?
Your function does return a float . But floats can hold integer values (an int is a perfectly valid float ) and what you are calculating and returning is a int .
What is the difference between division and integer division in Python?
The former is floating point division, and the latter is floor division, sometimes also called integer division. In Python 2.2 or later in the 2. x line, there is no difference for integers unless you perform a from __future__ import division , which causes Python 2.
What is the difference between division and modulo division?
In integer division and modulus, the dividend is divided by the divisor into an integer quotient and a remainder. The integer quotient operation is referred to as integer division, and the integer remainder operation is the modulus.
What happens when you divide an integer by an integer?
When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive. When you divide two integers with different signs, the result is always negative.
What happens when you divide an integer by another integer?
Following the rules stated above, when dividing integers with different signs the final answer (quotient) is negative. It is a negative quotient since we are dividing two integers that have different signs. Then we take that quotient and divide it by the integer that follows. We get –36 ÷ –9 = + 4.
Can a function return float value in C?
Cast the return value of a function that returns a floating point type to ensure predictable program execution. Subclause 6.8. 6.4, paragraph 3, of the C Standard [ISO/IEC 9899:2011] states: Function f() is allowed to return a value wider than float , but function g() (which uses the wider constant) is not.
Is float function in C?
C, C++, C# and many other programming languages recognize float as a data type. Other common data types include int and double. The float type can represent values ranging from approximately 1.5 x 10-45 to 3.4 x 1038, with a precision — the limit of digits — of seven.
How do you make a division into a float in C?
If you want the division to be a floating-point division, you’ll have to make the result a float: Notice that you’ll still divide integers, which will implicitly be cast to float: the result will be 3.0. To explicitly declare the operands as float, using the f suffix ( 13f, 4f ). Its just a basic operation.
Why does the / operator return a float in C++?
This is because of implicit conversion. The variables b, c, d are of float type. But the / operator sees two integers it has to divide and hence returns an integer in the result which gets implicitly converted to a float by the addition of a decimal point. If you want float divisions, try making the two operands to the / floats.
What is the difference between integer division and floating point division?
Calculating each digit involves the integer division of a number along with the remainder, rather than the floating point division of the number. Because of these (and other related) reasons, integer division results in an integer.
What are the rules for integer division in C?
See C# specification. In your case we have Integer division, with following rules applied: The division rounds the result towards zero, and the absolute value of the result is the largest possible integer that is less than the absolute value of the quotient of the two operands.
