在这种情况下,我们首先需要使用 parseFloat() 函数将数字转换为浮点数,然后再使用 toFixed() 将其四舍五入到小数点后两位。 例如: 代码语言:javascript 复制 constnumStr='17.23593';// 👇 convert string to float with parseFloat()constnum=parseFloat(numStr);constresult=num.toFixed(2);// 17.24console....

要使用定点表示法设置数字格式，只需使用toFixed方法：
The library is similar tobignumber.js, but here precision is specified in terms of significant digits rather than decimal places, and all calculations are rounded to the precision (similar to Python's decimal module) rather than just those involving division. ...
Historically, JavaScript may not have been considered a language where exact decimal numbers are even representable, to say nothing of doing (exact) calculations. In some application architectures, JS only deals with a string representing a human-readable decimal quantity (e.g,"1.25"), and never...
