测试代码

print("Binary number:", binary_number)
print("Decimal number:", decimal_number)
print("Decimal number:", binary_to_decimal("0101"))
print("Decimal number:", hex_to_decimal("000a"))
print("Decimal number:", dec2hex(10))
print("Decimal number:", dec2hex_f(10,4))
print("Decimal number:", dec2bin(10))
print("Decimal number:", dec2bin_f(10,4))
print("Decimal number:", dec2oct(10))
print("Decimal number:", dec2oct_f(10,4))

Decimal number: 10
Decimal number: 0xa
Decimal number: 000A
Decimal number: 0b1010
Decimal number: 1010
