如何显示小数值但删除小数

Question

假设我的价值为1.25美元。我希望只显示.25，但删除小数，这样我就可以显示你有1美元和25美分。

Answer 1

假设javascript和html很好，你可以这样做：

<div id="output"></div> 

<script>
var cost = 1.25;
var beforeDec = Math.abs((cost).toFixed(0));
var afterDec = 100*(cost - beforeDec);

if (beforeDec < 1) {
var dollar = " dollars";
} else {
var dollar = " dollar";
}

if (afterDec > 1) {    
var cent = " cents"; 
} else {
var cent = " cent";
}


document.getElementById("output").innerHTML = "You have " + beforeDec + dollar + " and " + afterDec + cent + ".";

</script>
