My issue

console.log(bmi.toFixed(2)+ " "+ bmicaterogy);
why we usebmi.toFixed(2) here

My code

const height = [1.70, 1.65, 1.80, 1.60, 1.75];
const weight = [30, 55, 90, 102, 65];

/* Using these 5 users find the BMI */
/* Update your code below this line */
for(let i =0;i<height.length;i++){
    
    const bmi=weight[i]/(height[i]*height[i]);
    let bmicaterogy;
    if(bmi<18.5){
        bmicaterogy="underweight";
    }else if (bmi>=18.5&&bmi<=24.9){
        bmicaterogy="normal weight";
    }else if (bmi>=25&&bmi<=29.9){
        bmicaterogy="Overweight";
    }else{
        bmicaterogy="obese";
    }
    console.log(bmi.toFixed(2)+ " "+ bmicaterogy);
}

The toFixed() method is used to format a number with a fixed number of digits after the decimal point. In this case, it formats the BMI value to have exactly two digits after the decimal point. This is often done for better readability or presentation of numerical data.
