JavaScript的left shift(<<)运算符中的转换规范在哪里 我想确定一下我在JavaScript数字处理方面的知识不足之处。 JS处理shift left运算符的方式显示了这个差距。 我的理解是,在JavaScript中,“所有的数字都是浮点数”。 但这并不适合位移位运算符,而且实际上,可演示的行为还告诉我,这比我意识到的还要多。 我检查...
The left shift indicates a leftward shift of each bit in binary encoding. Left shifting is an essential process when operating with binary numbers. For example, shifting the number 5 to the left by one position yields 10, or 1010. Similarly, shifting 10 by two positions to the left renders...
