ROUND_HALF_DOWN:向最近的值舍入,如果相等则向靠近0的方向舍入。 ROUND_HALF_EVEN:向最近的值舍入,如果相等则向偶数方向舍入。 2Division 首先分析一下floordivision的例子: >>>5//2,5.0//2,5//-2,5.0//-2 (2,2.0,-3,-3.0) 从以上例子中可以看出,跟C或者Java不同(采用ROUNDING_DOWN),Python的floo...

Rounding 1.5 to zero decimal places results in the value 2 (i.e. .5 is rounded upwards): round(1.5)# Round up to next even value# 2 However, rounding 2.5 results in the value 2 as well (i.e. .5 is rounded downwards): round(2.5)# Round down to next even value# 2 ...
Cent of 0.01 to 0.04 = Round down to 0 (zero) Cent of 0.05 = Remain as 0.05 Cent of 0.06 to 0.09 = round up as 0.10 By law in our country the currency need to be rounded in such way due to 1 cent coin is no longer a legal tender. Please share if anyone have solution. Thank...
In the following example, we round down an array of values using NumPy's floor() function −Open Compiler import numpy as np # Define an array of values values = np.array([3.14159, 2.71828, 1.61803, 0.57721]) # Round down each element to the nearest integer floored_values = np.floor...
Jan 11, 2017CJavaJavaScriptMathPython I made a small post aboutInexact rounding up or down with decimal digits. But it is also possible to run into the same bug when rounding floating point numbers to the next number with restricted decimal digits. A really common example is the price calcul...
