Final answer:
To determine if a number is an integer, you can write a function called isInteger(x) that checks if the given number is equal to its integer value.
Step-by-step explanation:
To determine if a number is an integer, you can write a function called isInteger(x) using programming languages like Python or JavaScript. Here's an example of how you can write the function in Python:
def isInteger(x):
if x == int(x):
return True
else:
return False
This function checks if the given number x is equal to its integer value. If it is, then it is an integer and the function returns True. Otherwise, it returns False.
