import { Typography } from "@mui/material";
function ProductPrize({}) {
const presentPrize = 125.0;
return (

JavaScript会打印出它所需的最少小数位数。如果你总是想要保留2位小数，你可以将代码更改为以下内容：
<Typography variant="h4" sx={{ fontWeight: "bold" }}>
{`$${(Math.round(presentPrize * 100) / 100).toFixed(2)}`}
</Typography>
这将四舍五入1.236为$1.24。
英文:
JavaScript prints out the minimum number of decimal points it needs to. If you always want 2 decimal points, you can change the code to the following:
<Typography variant="h4" sx={{ fontWeight: "bold" }}>
{`$${(Math.round(presentPrize * 100) / 100).toFixed(2)}`}
</Typography>
This with round 1.236 to $1.24
