Truncate number to two decimal places without rounding

Question

Suppose I have a value of 15.7784514, I want to display it 15.77 with no rounding.

var num = parseFloat(15.7784514);
document.write(num.toFixed(1)+\"


        

Answer 1

This worked well for me. I hope it will fix your issues too.

function toFixedNumber(number) {
    const spitedValues = String(number.toLocaleString()).split('.');
    let decimalValue = spitedValues.length > 1 ? spitedValues[1] : '';
    decimalValue = decimalValue.concat('00').substr(0,2);

    return '$'+spitedValues[0] + '.' + decimalValue;
}

// 5.56789      ---->  $5.56
// 0.342        ---->  $0.34
// -10.3484534  ---->  $-10.34 
// 600          ---->  $600.00

function convertNumber(){
  var result = toFixedNumber(document.getElementById("valueText").value);
  document.getElementById("resultText").value = result;
}


function toFixedNumber(number) {
        const spitedValues = String(number.toLocaleString()).split('.');
        let decimalValue = spitedValues.length > 1 ? spitedValues[1] : '';
        decimalValue = decimalValue.concat('00').substr(0,2);

        return '$'+spitedValues[0] + '.' + decimalValue;
}
