将十进制转换为二进制的代码

将十进制数转换为二进制可以使用编程语言中的内置函数或通过位操作实现。这里以Python为例,你可以使用`bin()`函数:
```python
def decimal_to_binary(n):
return bin(n).replace("0b", "") # 去掉前缀 "0b"
# 示例
decimal_number = 42
binary_representation = decimal_to_binary(decimal_number)
print(f"{decimal_number} in binary is {binary_representation}")
```
如果你想手动实现转换过程,可以采用循环并不断除以2取余的方法:
```python
def decimal_to_binary_custom(n):
binary = ""
while n > 0:
binary = str(n % 2) + binary
n = n // 2
return binary
binary_representation_custom = decimal_to_binary_custom(decimal_number)
print(f"{decimal_number} in binary (custom method) is {binary_representation_custom}")
```
