5.0 / 2 returns the floating-point number 2.5, and int(2.5) returns the integer 2 with the .5 removed.Integer DivisionIf writing int(5.0 / 2) seems a little long winded to you, Python provides a second division operator called the integer division operator (//), also known as the ...
as expected, a float. For example, Java uses integer division that skips the remainder, i.e., no decimal values, so it will always return a whole number. This is a common source of errors.
DivisionThere are two division operators in Python, and fractions support both of them:True division: / Floor division: //The true division results in another fraction, while a floor division always returns a whole number with the fractional part truncated:...

你将了解基本三角函数及其应用之间的关系,比如著名的毕达哥拉斯定理。你将练习向量微积分,并通过在 Python 中进行向量代数来了解它的适用性。最后,你会感到高兴,因为复数并不比其他类型的数字差;它们与三角学密切相关,并且对现实世界的应用很有用。 介绍
