What happen when an integer value is assigned to an float variable?

Output. Here in this code, we can see that if we pass an integer value to a float then it will act as an integer and returns an integer value as output.

What will happen if you cast a float to an integer?

Since a float is bigger than int, you can convert a float to an int by simply down-casting it e.g. (int) 4.0f will give you integer 4. So if your float value is 3.999, down casting to an integer will produce 3, not 4. If you need rounding then consider using the Math.

Can we compare float values in C?

The short answer is that due to the way floating point numbers are represented, you cannot do basic comparison or arithmetic and expect it to work.

Can we store integer value in float?

So you cannot store a float value in an int object through simple assignment. You can store the bit pattern for a floating-point value in an int object if the int is at least as wide as the float , either by using memcpy or some kind of casting gymnastics (as other answers have shown).

Can we compare int and float in Java?

The compare() method of Float Class is a built-in method in Java that compares the two specified float values. The sign of the integer value returned is the same as that of the integer that would be returned by the function call.

What is the difference between integer and float variables?

Integers and floats are two different kinds of numerical data. An integer (more commonly called an int) is a number without a decimal point. A float is a floating-point number, which means it is a number that has a decimal place. Floats are used when more precision is needed.

What will happen if you cast a float to an integer Python?

When converting floats to integers with the int() function, Python cuts off the decimal and remaining numbers of a float to create an integer. Even though we may want to round 390.8 up to 391, Python will not do this through the int() function.

Can we compare integer and float?

As to the first question about whether the comparison is valid, the answer is yes. It is perfectly valid. If you want to know if a floating point value is exactly equal to 3, then the comparison to an integer is fine. The integer is implicitly converted to a floating point value for the comparison.

What is a better way to compare floating point values?

To compare two floating point or double values, we have to consider the precision in to the comparison. For example, if two numbers are 3.1428 and 3.1415, then they are same up to the precision 0.01, but after that, like 0.001 they are not same.

How do floating point variables compare?

If we do have to compare two floating-point numbers then rather than using “==” operator we will find the absolute difference between the numbers (which if were correctly represented, the difference would have been 0) and compare it with a very small number 1e-9 (i.e 10^-9, this number is very small) and if the …

How a negative integer will be stored in C?

4 Answers. The C standard doesn’t mandate any particular way of representing negative signed numbers. In most implementations that you are likely to encounter, negative signed integers are stored in what is called two’s complement. The other major way of storing negative signed numbers is called one’s complement.

Is integer same as float?

Why do floats compare to integers?

So as long your floats come from non decimal literals, the comparison with the equivalent integer will be the same, because the integer will be cast to the very same float before the comparison can be done.

What is the difference between float and int in C++?

On most C/C++ implementations, float and int have the same size (4 bytes) and wildly different precision levels. Neither type can hold all values of the other type.

Is an int-float comparison valid?

What most people do, if an int-float comparison is really necessary, is pick some threshold of tolerance and go with that, like so: I am going to buck the trend here a bit. As to the first question about whether the comparison is valid, the answer is yes. It is perfectly valid.

What happens when you cast a float to INT?

When you cast a float to int (e.g, 1.0f to 1 ), their memory are not the same. Comparison in floating-point types works the same as in integer types for normal types. a == b always return true if the value of a is exactly equal to b, i.e 12.345 == 12.345 but 12.345 < 12.346.
