Nettet27. mai 2011 · You can use the mod function, which returns the remainder after division. All integers are divisible by 1. So a good test for non-integer would be. integerTest=~mod (value,1); This returns 0 if value is not an integer and 1 if it is. You can then use this as a conditional to reject non-integer user inputs. Share.
NettetThe greatest integer function is also known as the step function. It rounds up the number to the nearest integer less than or equal to the given number. The greatest integer function has a step curve which we will explore in the following sections.
