When making sums of decimal values in Javascript (in the example with two decimal places). Sometimes the sum generates a result with 'n' decimal places other times not.
The question is:
Why does that happen?
How to standardize the result the way you want it.
Example.
document.getElementById("exemplo").innerHTML = 1.25+1.36
document.getElementById("exemplo2").innerHTML = 1.25+1.37<div id="exemplo"></div>
<div id="exemplo2"></div>0
You can use Math to round the spool, or simply make the conversion to float.
Math.floor(1.25+1.36) //Resultado 2 , Valor arrendado para baixo
Math.ceil(1.25+1.36) //Resultado 3 , Valor arrendado para cima
parseFloat(1.25+1.37) //Resultado 2.62
-1
is very simple to solve
use the parseFloat()
document.getElementById("exemplo").innerHTML = parseFloat(1.25+1.37)
document.getElementById("exemplo2").innerHTML = parseFloat(1.25) + parseFloat(1.37)<div id="exemplo"></div>
<div id="exemplo2"></div>Browser other questions tagged javascript
