python代码编程助手 在Python中,可以使用round()函数将数字x四舍五入到小数点后两位。以下是一个示例函数: python def round_to_two_decimals(x): """ 将数字x四舍五入到小数点后两位。 参数: x (float or int): 要四舍五入的数字。 返回: float: 四舍五入到小数点后两位的结果。 """ return round...
对于金额的显示,大多情况下需要保留两位小数,比如下面的(表格采用 element-ui): 在vue.js中,对文本的处理通常是通过设置一系列的过滤器,过滤器可以用在两个地方:双花括号插值 和 v-bind 表达式 (后者从 2.1.0+ 开始支持). 定义过滤器 filters: { rounding (value) { return value.toFixed(2) } } toFixed...

python 2的官网文档:https://docs.python.org/2/library/functions.html?highlight=round#round Values are rounded to the closest multiple of 10 to the power minus ndigits; if two multiples are equally close, rounding is done away from 0 (so, for example, round(0.5) is 1.0 and round(-0.5)...

在python2.7的doc中,round()的最后写着,"Values are rounded to the closest multiple of 10 to the power minus ndigits; if two multiples are equally close, rounding is done away from 0." 保留值将保留到离上一位更近的一端(四舍六入),如果距离两端一样远,则保留到离0远的一边。所以round(0.5)...
