Last Updated : October 07, 2021

Problem Statement

In this program, we will create an integer variable then we will assign the value of the integer variable by converting it into a float variable using the "as" keyword.

Program/Source Code

The source code to convert an integer number into a float number is given below. The given program is compiled and executed successfully.

// Rust program to convert an 
// integer number into a float number

fn main() 
{
    let mut intVar:i32  = 5;
    let mut floatVar:f32 = 0.0;
    
    floatVar=intVar as f32;
    println!("Number is : {}",floatVar);
}

Output

Number is : 5

Explanation

Here, we created a variable intVar of the i32 type. Then we assigned the value of the intVar variable into the floatVar variable using the as keyword. After that, we printed the result.
