Hence, we will use the data frameround()method along with theastype()method for converting the float value to an integer value and getting the round-off result of these values. Let us assume that we have a value of 1.6 the round method will convert this value into 2 whereas the same ...
Theround() functionis a built-in function in Python that rounds a number to the nearest value and hence we can convert float to int Python. It can operate on both integers and floating-point numbers. Theround() functionin Pythonrounds a number up if the fractional part is 0.5 or higher ...

Converting Float to Int in Python Python provides a built-in functionint()that can convert a float to an integer. This function truncates the decimal part and returns the integer part of the float. float_num=10.6int_num=int(float_num)print(int_num)# Output: 10 In this example, the flo...
float also accepts the strings “nan” and “inf” with an optional prefix “+” or “-” for Not a Number (NaN) and positive or negative infinity.>>> int(10.9898) 10 >>> int('10.9898') # 解释器抛出 ValueError,并给出基本描述 Traceback (most recent call last): File "<stdin>", ...
分数转浮点数:float函数可以直接将Fraction对象转换成浮点数 >>> z Fraction(1, 4) >>> float(z) 0.25 表达式中允许分数和浮点数混合使用: >>> x Fraction(1, 3) >>> x + 2 # Fraction + int -> Fraction Fraction(7, 3) >>> x + 2.0 # Fraction + float -> float 2.3333333333333335 >>...

这个实验的核心,sum_real是对照组, sum_float是实验组,sum_real进行整数累加,sum_float进行浮点数累加 因为计算机整数相加不会丢失精度,而浮点会丢失,详细可以参考:去看看 而正常来讲,sum_real / 100 应该是等于 sum_float 但是实际上, 在上面的例子里,就出现了错误, ...
