如何使用jQuery在输入中的浮点值中的点后隐藏数字

Question

I am developing a financial calculator and i am facing a problem to get exact answers if i round the value . Basically i dont want to show numbers after dot in float value, but i need the same float value in my calculations. Note :- There are too many calculations so it is tough to save values in variables

for example

value1 = Math.round(34.55); // it will be 35
$('#input1').val(value1); // and it is fine to show round value which is 35
value2 = ("#input1").val(); // In this line it will be 35 but i need 34.55

Answer 1

try this

var floatVal = 34.55;
value1 = Math.round(floatVal); // it will be 35 
$('#input1').attr("data-floatVal","34.55");
$('#input1').val(value1);
//it's important to parseFloat
value2 = parseFloat($("#input1).attr("data-floatVal")); 

Answer 2

set it as an attribute of that input element

var decimalValue = 34.55;
$('#input1').attr( "data-value", decimalValue );
$('#input1').val( Math.round( decimalValue ) ); 
value2 = ("#input1).val(); //decimal value
actualValue2 = ("#input1).attr( "data-value" ); // float value

Answer 3

try this //I hope this will work for you. roundValue = Math.round(34.55); actualValue=34.55;//Create another variable to store actual value and use when required. $('#input1').val(roundValue);

value2 = actualValue;

 try this //I hope this will work for you. roundValue = Math.round(34.55); actualValue=34.55;//Create another variable to store actual value and use when required. $('#input1').val(roundValue); value2 = actualValue;
