The usual way to do that is to first convert the integer to a floating point number, and then do the multiply in floating point. In current hardware, floating point multiply is about the same speed as integer multiply, so you don’t gain anything by doing the multiply with integers.

## Can we multiply float and int?

Our error is a TypeError. When you multiply a string by an integer, it creates a repeating sequence of that string. … **Strings cannot be multiplied by floating** point numbers.

## Can we multiply float and double in Java?

However, although you’d expect this to return **x = 50** , instead x = 0 ! The same thing happens when I use float d = 0.5f .

## How do you multiply a float in Java?

Example: **Multiply** Two **Floating**-Point Numbers

first and second are then **multiplied** using the * operator and the result is stored in a new **float** variable product . Finally, the result product is printed on the screen using println() function.

## How do you multiply double and integer in Java?

**“java multiply double and int” Code Answer**

- class Scratch{
- public static void main(String[] args){
- double decimal = 5.7;
- System. out. println( (int) decimal ); //casting.
- System. out. println( Math. …
- System. out. println( decimal % 1); // modulus.
- System. out. println( Integer. …
- }

## Can we convert float to int in Python?

A float value can be converted to an int value **no larger than the input by using the** math. floor() function, whereas it can also be converted to an int value which is the smallest integer greater than the input using math. ceil() function.

## What is a double vs float?

**A double is 64 and single precision (float) is 32 bits**. The double has a bigger mantissa (the integer bits of the real number). Any inaccuracies will be smaller in the double.

## What is the difference between float and double Java?

Double takes more space but more precise during computation and **float takes less space** but less precise. According to the IEEE standards, float is a 32 bit representation of a real number while double is a 64 bit representation. In Java programs we normally mostly see the use of double data type.

## How do I convert float to int in Java?

**Cast Conversion**

- public 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);
- }

## What does a double do in Java?

Java double is used to **represent floating-point numbers**. It uses 64 bits to store a variable value and has a range greater than float type.

## How do you declare a float in Java?

Floating-point numbers are numbers that have fractional parts (usually expressed with a decimal point). You should use a floating-point type in Java programs whenever you need a number with a decimal, **such as 19.95 or 3.1415**. Java has two primitive types for floating-point numbers: float: Uses 4 bytes.

## How do you swap two numbers in Java?

**Java Program**

- import java.util.*;
- class Swap_With {
- public static void main(String[] args) {
- int x, y, t;// x and y are to swap.
- Scanner sc = new Scanner(System.in);
- System.out.println(“Enter the value of X and Y”);
- x = sc.nextInt();
- y = sc.nextInt();

## How do you multiply in Java?

**In order to multiply numbers in Java, we will use the asterisk (*) between each number or variable.**

- int x = 12;
- int y = 13;
- int z = x * y;
- System. out. println(“Multiplication: ” + z);
