Can We Add Int And Float In Java?

Can we compare int and float in Java?

1 Answer.

Yes, your specific example is fine, since both 0 and 1 can be exactly represented as a float .

Note that, unlike float , double has wide enough mantissa to store every 32-bit int value.

However, there are long values that cannot be represented as double s..

How do I convert float to int in Java?

Cast Conversionpublic static void main(String[] args) {//casting.//you need to f to tell java its float!float rate = 19.98f;int intRate = (int) rate;System. out. println(“Value ” + rate + ” casted to int = ” + intRate);}

How do you convert long to int?

Java Long to int Examplepublic class LongToIntExample2{public static void main(String args[]){Long l= new Long(10);int i=l.intValue();System.out.println(i);}}

How do you compare two float 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.

Can you add an int to a float?

Yes, an integral value can be added to a float value. The basic math operations ( + , – , * , / ), when given an operand of type float and int , the int is converted to float first. … However, 15/2 does an integer division, so produces the result 7 (there is no implicit conversion to float here).

How do you divide a float in C++?

If either (or both) of the operands are floating point values, the division operator performs floating point division. Floating point division returns a floating point value, and the fraction is kept. For example, 7.0 / 4 = 1.75 , 7 / 4.0 = 1.75 , and 7.0 / 4.0 = 1.75 .

Can we compare int 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.

How do you compare floats in Java?

The comapre() 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. Parameters: The function accepts two parameters: f1: The first float value to be compared.

Can a long be negative Java?

One of the tricky parts of this question is that Java has multiple data types to support numbers like byte, short, char, int, long, float, and double, out of those all are signed except char, which can not represent negative numbers.

Can we add int and long in Java?

Yes, you can add a long and an int just fine, and you’ll end up with a long . The int undergoes a widening primitive conversion, as described in the Java Language Specification, specifically JLS8, §5.1. 2 .

How do you divide two numbers in C++?

Divide Two Integers in C++Taking two arguments x and y it indicates x divides y.if x < -Infinity and y = 1, then return infinity.a := |x|, b := |y| and ans := 0.while a – b >= 0. p := 0. … if x > 0 is true and y > 0 is also true, then return ans, otherwise return (– ans)

Can you add int and double in Java?

When one operand is an int and the other is a double, Java creates a new temporary value that is the double version of the int operand. For example, suppose that we are adding dd + ii where ii is an int variable. Suppose the value of ii is 3. Java creates a temporary value 3.0 that is the corresponding double value.

How do I convert an int to a string in Java?

Different ways for Integer to String Conversions In JavaConvert using Integer.toString(int) The Integer class has a static method that returns a String object representing the specified int parameter. … Convert using String.valueOf(int) … Convert using Integer(int).toString() … Convert using DecimalFormat. … Convert using StringBuffer or StringBuilder. … Convert with special radix.

How do you divide a remainder in C++?

The remainder is obtained by using the modulus operator on dividend and divisor. quotient = dividend / divisor; remainder = dividend % divisor; After that the dividend, divisor, quotient and remainder are displayed.

Can you divide a double by an int C++?

In this example, the division happens first. Because this is an int divided by a double, the compiler handles this by converting the int into a double. Thus, the result of b / d is a double. … This is an int plus a double, so C++ converts the int to a double, and the result is a double.
