To convert large binary strings into decimal numbers you can use theArray.prototype.reduceRight()method (introduced in ES5) along withBigInt(introduced in ES10) like so: // ES10+functionbin2dec(binStr) {constlastIndex = binStr.length-1;returnArray.from(binStr).reduceRight((total, cu...
所以 4.5 最终表示为（M=001、E=1025）：(图片由此生成 http://www.binaryconvert.com/convert_double.html )下面再以 0.1 例解释浮点误差的原因， 0.1 转成二进制表示为 0.0001100110011001100 (1100 循环)， 1.100110011001100x2^-4 ，所以 E=-4+1023=1019 ；M 舍去首位的 1，得到 100110011... 。
JavaScript provides typed arrays that allow you to work with binary data in a more efficient and structured manner. Typed arrays provide a set of numeric types (e.g., Int8Array, Uint8Array) that can be used to store and manipulate binary data. To convert binary data to a bytearray using...
BigInt 字面量写为一个由数字组成的字符串,后面跟着一个小写字母n。默认情况下,它们是以 10 进制表示的,但你可以使用0b、0o和0x前缀来表示二进制、八进制和十六进制的 BigInt: 代码语言:javascript 复制 1234n // A not-so-big BigInt literal 0b111111n // A binary BigInt 0o7777n // An octal ...

It will convert the float value to an integer. Underneath at the binary level, the bitwise right SHIFT operator shifts the binary bits of the operand to the right by a count specified by the second operand. Hence, it ignores the bits that overflow to the right. In doing so, the ...
