def even_odd_decimal(num): if num%1!=0: return num "is decimal" elif num%2==0: return num "is even" else: return num "is odd"

The function even_odd_decimal(num) is intended to check if a number is decimal, even or odd. However, there are some syntax errors in the function. Here is the corrected version:

def even_odd_decimal(num):
    if num % 1 != 0:
        return str(num) + " is decimal"
    elif num % 2 == 0:
        return str(num) + " is even"
    else:
        return str(num) + " is odd"

Here's how it works:

1. The function takes a number as an argument.
2. It first checks if the number is a decimal by checking if the remainder of the division of the number by 1 is not equal to 0. If it is a decimal, it returns a string stating that the number is decimal.
3. If the number is not a decimal, it checks if the number is even by checking if the remainder of the division of the number by 2 is equal to 0. If it is even, it returns a string stating that the number is even.
4. If the number is neither a decimal nor even, it means the number is odd. So, it returns a string stating that the number is odd.
