AI代码解释 (1)s:string,字符串;(2)d:decimal integer,十进制数;(3)i:integer,用法同%d;(4)u:unsigned integer,无符号十进制数;(5)f:float,浮点数(默认保留小数点后6位);(6)F:Float,浮点数(默认保留小数点后6位);(7)e:exponent,将数字表示为科学计数法(小写e,默认保留小数点后6位);(8)E:Expone...
Python uses the math module, NumPy, and Pandas libraries to offer different methods of rounding up numbers. Round up using the math module The math.ceil() function from math is used to round up a number to the nearest integer. The syntax is shown below. # Import the math module to acce...
round() Syntax round(number, ndigits) round() Parameters Theround()function takes two parameters: number- the number to be rounded. ndigits (optional)- number up to which the given number is rounded; defaults to0. round() Return Value Theround()function returns the nearest integer to the ...
ROUND_HALF_UP 类似于 ROUND_HALF_DOWN,不过如果最后一位有效数字为 5,值会朝 0 的反方向取整。ROUND_UP 朝 0 的反方向取整。ROUND_05UP 如果最后一位是 0 或 5,则朝 0 的反方向取整;否则向 0 取整。 [python] view plain copy import decimal context = decimal.getcontext() ROUNDING_MODES = [ '...
You may notice that round_up() looks a lot like truncate(). First, you shift the decimal point in n the correct number of places to the right by multiplying n by 10**decimals. You round this new value up to the nearest integer using math.ceil(), and then you shift the decimal ...
ROUND_FLOOR (towards-Infinity), 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). ...
print(Decimal("1.125").quantize(Decimal(".00"), rounding=ROUND_HALF_UP)) >>> 1.13 __str__和__repr__ 格式化字符参数中有一个%r, 此处的r即是调用__repr__魔法方法,其功能和__str___类似,二者区别如下: class Animal: def __init__(self, name): ...

The round() Function in Python: Example Here, we take a look at how you can use the Python function round() next time you need it: Code # Rounding off integers using round() print("Round integer 33: ") print(round(33)) # Rounding off floating point, to show that at 0.5, it ro...
字符串格式化相当于字符串模板。也就是说，如果一个字符串有一部分是固定的，而另一部分是动态变化的，...
