有理数是整数(正整数、0、负整数)和分数的统称,是整数和分数的集合。 整数也可看做是分母为一的分数。不是有理数的实数称为无理数,即无理数的小数部分是无限不循环的数。是“数与代数”领域中的重要内容之一,在现实生活中有广泛的应用,是继续学习实数、代数式、方程、不等式、直角坐标系、函数、统计等数学内容以及相关学科知识的基础。 有理数集可以用大写黑正体符号Q代表。但Q并不表示有理数,有理数集与有理数是两个不同的概念。有理数集是元素为全体有理数的集合,而有理数则为有理数集中的所有元素。

有理数采样速率转换可以划分为整数倍和分数倍采样率转换。
Rational ratio conversion can be realized by integer and fraction ratio conversion.
They're irrational numbers and these irrational numbers like to move to rational numbers; they like to move to consonances; they like to move to intervals that are based on things such as two to one and three to two or maybe four to three.
它们是无理数,而这些无理数想要变为有理数,它们想变成和谐音,就要根据一些比率改变音程,比如二比一,三比二,或四比三的比率
And that idea was, we make a guess in the middle, we test it so this is kind of a guess and check, and if the answer was too big, then we knew that we should be looking over here. If it was too small, we knew we should be looking over here, and then we would repeat.
这些有理数是有序排列的,然后我们的想法是,首先在中间取个数作为猜想数,然后对这个猜想数进行验证,如果由猜想数得到的答案太大,我们知道应该跳过,比猜想数大的那个区间,如果太小的话。
