Python提供了一个内置函数int()来将字符串或浮点数转换为整数。我们可以使用该函数来将科学计数法表示的数字转换为整数。 下面是一个示例代码,演示了如何使用int()函数将科学计数法转换为整数。 # 将科学计数法转换为整数的函数defconvert_scientific_to_integer(scientific_notation):integer_value=int(float(scientific...
Also, a logical error can occur when you pass a string representing a number in a different base toint(), but you fail to specify the appropriate base. In this case,int()will convert the string to decimal without syntax errors, even though you intended a different base. As a result, y...

Method 1: Use the int() Function (Basic Truncation) The most simple way to convert a float to an integer in Python is by using the built-inint()function. float_number = 7.85 integer_number = int(float_number) print(integer_number) ...
