numbers and text in same field

Question

I can't get the numbers and text in same form field to force two decimal places or do Total figure.

This is the link .

I am trying to get the last 3 cells to work with two decimal places. eg Total sq mt figure x Price should calculate the Cost cell.

Also want to get the Cost cell (NaN) working ! Thanks.

Answer 1

In general, you want to do something like this

function calc(val1, val2) { // this is NOT a replacement for your Calculate function
    val1 = parseFloat(val1.replace(/[^\d\.-]/g, ''));
    val2 = parseFloat(val2.replace(/[^\d\.-]/g, ''));
    return (val1 * val2).toFixed(2);
}

NOTE: the above returns a STRING

and STOP redefining with Math.round in your code

Answer 2

var result = Math.round(num * 100.0) / 100.0;

应该用两位小数位格式化您的数字。
