decimal可以通过指定rounding参数来确定进位方式。如果在一定情况下没有指定参数rounding,那么默认使用上下文提供的进位方式,上下文的进位方式我们可以这样来查看: fromdecimalimportgetcontextprint(getcontext().rounding) 输出ROUND_HALF_EVEN,即Round to nearest with ties going to nearest even integer方式进行进位。 我们...
ROUND_HALF_DOWN (to nearest with ties going towards zero), ROUND_HALF_EVEN (to nearest with ties going to nearest even integer), ROUND_HALF_UP (to nearest with ties going awayfromzero),orROUND_UP (awayfromzero). ROUND_05UP (awayfromzeroiflast digit after rounding towards zero would have bee...
Round to nearest with ties going to nearest even integer. decimal.ROUND_HALF_UP Round to nearest with ties going away from zero. decimal.ROUND_UP Round away from zero. decimal.ROUND_05UP Round away from zero if last digit after rounding towards zero would have been 0 or 5; otherwise roun...
int函数虽然使用ROUND DOWN方式,但是是取整,得到的结果是integer。如果你的需求是要保留小数点后几位,就要使用decimal模块的接口: >>> from decimal import * >>> Decimal('1.2222').quantize(Decimal('.00'), rounding=ROUND_DOWN) Decimal('1.22') ...
Third, make sure that you’re rounding to the nearest integer. If you don’t specify the number of decimal places, Python rounds to the nearest whole number. So, think about the reasons you have behind using the ROUND function. Otherwise, you may not round in the right way or to the ...
简介 python标准库的解释及翻译round(number[, ndigits])Return the floating point value number rounded to ndigits digits after the decimal point. If ndigits is omitted, it returns the nearest integer to its input. Delegates to number.__round__(ndigits).For the built-in...
