Float64Array类型数组代表的是平台字节顺序为64位的浮点数型数组(对应于 C 浮点数据类型) 。 如果需要控制字节顺序, 使用DataView替代。其内容初始化为0。一旦建立起来,你可以使用这个对象的方法对其元素进行操作,或者使用标准数组索引语法 (使用方括号)。 语法 代码语言:javascript 复制 newFloat64Array();// new ...

About stdlib... We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution ...

Interactive API reference for the JavaScript Float64Array Object. Float64Array is similar to an Array where each item is a 64 bit (8 byte) floating point number (the same as the standard Number type).
Different ways to create a Float64Array // From a length var float64 = new Float64Array(2); float64[0] = 42; console.log(float64[0]); // 42 console.log(float64.length); // 2 console.log(float64.BYTES_PER_ELEMENT); // 8 // From an array var arr = new Float64Array([21,...
