If a value is a character string literal, the _binary introducer may be used to designate it as a binary string. For example: _binary 'a' The _binary introducer is permitted for hexadecimal literals and bit-value literals as well, but unnecessary; such literals are binary strings by defau...
Unit = unit:IntegerLiteral 有效范围是1-256,integer、float和bitstring默认是1,binary默认是8 X=<<15,25,35>> ,默认每一个元素Size为8位(也即一个字节),等效于<<15:8,25:8,35:8>>,通过byte_size(X)可以得到X在内存中共占用3字节,内存中的内容为0x0F1923 ...
If you start with a hexadecimal literal, then you can convert it to text representing its binary value usingdec2bin. D = 0x8F; binStr = dec2bin(D) binStr = '10001111' Bitwise Operations with Binary Values One typical use of binary numbers is to represent bits. For example, many devic...
