WebSome languages (like C/C++) provide ways of storing boolean values as single bits, if these bits are bundled in a single byte. In other words, in C, you can store eight booleans in a byte. But few ever use this since memory is cheap and processors manipulate data in 8/16/32/64 bit chunks. – Gort the Robot Jan 29, 2013 at 2:51 Web每种数据类型都有下面的这些方法,可以转化为其它的类型: toByte(): Byte toShort(): Short toInt(): Int toLong(): Long toFloat(): Float toDouble(): Double toChar(): Char 有些情况下也是可以使用自动类型转化的,前提是可以根据上下文环境推断出正确的数据类型而且数学操作符会做相应的重载。 例如下面是正确的: val l = 1L + 3 // Long + Int => Long 位操作符 对 …
