ROUND_HALF_EVENT 和 ROUND_HALF_DOWN:EVENT是quansize的默认设置值,可以通过getcontext()得到,EVENT由于达不到四舍五入所以不进位,DOWN同样也不进位。 ROUND_CEILING 和 ROUND_FLOOR:CEILING倾向正无穷不进位,FLOOR即使没有超过5,但是为了总是变得更小进了一位。 ROUND_UP 和 ROUND_DOWN:UP始终进位,DOWN始终不...
参考链接: Python int() 猛的一看 int() round() math.floor() 这几个函数函数好像做的是同一件事情,很容易将他们弄混,下面是他们的一些不同之处: int()函数直接截去小数部分...floor() 得到最接近原数但是小于原数的部分round()得到最接近原数的整数(返回为

Round to nearest, ties away from zero – rounds to the nearest value; if the number falls ...
However, the other way (round away from zero) is taught in school most of the time, so banker's rounding is likely not that well known. Furthermore, some of the most popular programming languages (for example: JavaScript, Java, C/C++, Ruby, Rust) do not use banker's rounding either....
29. How to round away from zero a float array ? 30. How to find common values between two arrays? 31. How to ignore all numpy warnings (not recommended)? 32. Is the following expressions true? 33. How to get the dates of yesterday, today and tomorrow?
2. Round it to the nearest whole number, unless it ends in exactly .5 3. If it ends in exactly .5, then round towards the nearestevenwhole number 4. Multiply it by the unit to which it is to be rounded Examples(rounded to hundredths): ...
The round() function can round the values up and down both depending on the situation. For <0.5, it rounds down, and for >0.5, it rounds up. For =0.5, the round() function rounds the number off to the nearest even number. So, 0.5 is rounded to zero, and so is -0.5; 33.5 and...
round(Money('2.5', 'EUR')) Returns 3.0, a float rounded amount away from zero. Returns EUR 2, a Money object with rounded amount to the nearest even. Money('0', 'EUR').amount < '0' Returns True. This is the weird but expected behaviour in Python 2.x when comparing Decimal object...
