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 types...
The floor of the scalar `x` is the largest integer `i`, such that `i <= x`. It is often denoted as :math:`\lfloor x \rfloor`. 标量“ x”的下限是最大的整数“ i”,因此“ i <= x”。 它通常表示为:\ lfloor x \ rfloor`。 Parameters --- x : array_like Input data. out...
Note that precision=0 returns a float (3.0) rather than an integer, unlike when no precision is specified (which returns an integer). Floating Point ConsiderationsDue to floating point representation, some results may be surprising. This example demonstrates cases where rounding might not behave as...
(), values are rounded to the closest multiple of 10 to the power minusndigits; if two multiples are equally close, rounding is done toward the even choice (so, for example, bothround(0.5)andround(-0.5)are0, andround(1.5)is2). The return value is an integer if called with one ...

Python 2.7 Round 6# Find the divisors!1 Create a function named divisors that takes an integer and returns an array with all of the integer's divisors(except for 1 and the number itself). If the number is prime return the string '(integer) is prime'2 用到点数学知识，...
Docstring: Rounding an Integral returns itself. Rounding with an ndigits argument also returns an integer. Type: builtin_function_or_method Python 整数与 Python 浮点数有不同的实现。 Python 列表和字符串对此没有定义,因此 round([1,2,3]) 将返回 AttributeError: 'list' object has no attribute ...
