Submitted by Nidhi, on October 07, 2021

Problem Solution:

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

Program/Source Code:

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

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

fn main() 
{
    let mut floatVar:f32 = 5.64;
    let mut intVar:i32 = 0;
    
    intVar = floatVar as i32;
    println!("Number is : {}",intVar);
}

Output:

Number is : 5

Explanation:

Here, we created a variable floatVar of the f32 type. Then we assigned the value of the floatVar variable into the intVar variable using the "as" keyword. After that, we printed the result.
