6.58 Other Built-in Functions Provided by GCC(点击打开链接)这个页面最后面三个函数就是我们需要的: — Built-in Function: uint16_t __builtin_bswap16 (uint16_t x) Returns x with the order of the bytes reversed; for example, 0xaabb becomes 0xbbaa. Byte here always means exactly 8 bits./...
每一个内置对象都是本地对象。 本地对象包含:Object、Function、Array、String、Boolean、Number、Date、RegExp、Error、EvalError、RangeError、ReferenceError、SyntaxError、TypeError、URIError。 内置对象包含 Global和Math。Global,在JS中(不是ECMAScript)根本没这么个东西,不能像Math.sin来引用Global中的方法,可以理解...

such as databases and foreign function interfaces to other programming languages. Many external systems already natively support decimal numbers. In such a setting, JavaScript is then the lower common denominator. With decimals in JavaScript, one has the confident that the numeric data one consumes ...
