$hexadecimal = 'A37334';echo base_convert($hexadecimal, 16, 2);//输出 101000110111001100110100 base_convert (PHP 3 >= 3.0.6, PHP 4, PHP 5) 1. 2. 3. base_convert -- 在任意进制之间转换数字 说明 string base_convert ( string number, int frombase, int tobase ) 1. 返 回一字符串,包...
所以在我们将十六进制转换成有符号的整数之前,我们需要定义一个函数来执行二进制补码运算。def twosComplement_hex(hexval): bits = 16 # Number of bits in a hexadecimal number format val = int(hexval, bits) if val & (1 << (bits - 1)): val -= 1 << bits return val 二进制值中最左边的...
让我们使用这个函数将十进制小数123.45转换为二进制和十六进制小数: decimal=123.45binary=decimal_to_n(decimal,2)hexadecimal=decimal_to_n(decimal,16)print(f'Binary:{binary}')print(f'Hexadecimal:{hexadecimal}') 1. 2. 3. 4. 5. 6. 输出: Binary: 1111011.01110 Hexadecimal: 7B.74 1. 2. 正如你所...
