A typed array constructor which returns a typed array representing an array of double-precision floating-point numbers in little-endian byte order. var arr = new Float64ArrayLE(); // returns <Float64ArrayLE> Float64ArrayLE( length ) Returns a typed array having a specified length. var arr...
byteOffset; // returns 0 Float64ArrayFE.prototype.BYTES_PER_ELEMENT Number of bytes per view element. var arr = new Float64ArrayFE( 'little-endian', 5 ); var nbytes = arr.BYTES_PER_ELEMENT; // returns 8 Float64ArrayFE.prototype.length Read-only property which returns the number of ...

任何数字在计算机中都是用0和1二进制来表示，对于float（占据4字节）和double（占据8字节）类型，又是...
Now they are currently in network byte order, or Big Endian and need to be converted to Little Endian. So then we have this... 0xC6332B8D 0x44C38F69 0x424252C5 - Respectivly...NOTE: The endian converter in the code handles this with the input, so this is just for ease of readin...
