Options include: scanf, sscanf, strtoul, atoi, and others. NaN == 0 is false, so in each of those cases, the result of the test would be false, indicating that the values are not integers. But if you tried the one above, floor(inf)==inf then the result would be true, seemingly indicating that it is an integer when it is not.

    Input.GetTouch returns Touch for a selected screen touch (for example, from a finger or stylus). Touch describes the screen touch. The index argument selects the screen touch. Input.touchCount provides the current number of screen touches. If Input.touchCount is greater than zero, the GetTouch index sets which screen touch to check. Touch returns a struct with the screen touch details. 06/01/2010В В· you mean I'll add these methods to the code above? Hmmm... what I want is to make the lines shorter... well, thanks for the help. =) I think this code is okay.

    Learn: How to check whether a bit is SET (High) or not using C programming language? Here, we will read a number and bit and check input bit is SET or not. Bitwise AND Operator (&) is used to check whether a bit is SET (HIGH) or not SET (LOW) in C and C++ programming language. Bitwise AND Operator (&) is a binary operator, which operates on two operands and checks the bits, it returns 1, if 16/03/2008В В· No actually. I've parsed as an int and it works just fine. If you had only checked the code. I'm trying to make an if statement, in order to declare d as either an int, or a double, depending on the result of the user's input.

    28/05/2013В В· With an input of q2 scanf returns 0. So far so good. However in a case like 1q2 (user meant to input 112) scanf will convert the 1 stop on the q, leave the q2 in the input stream and return 1. Not want you want. The most robust way is to roll your own, just take in the user input, whatever it is, and convert and validate it yourself. 16/08/2012В В· From the MSDN help page for Enumerable.Distinct: "Returns distinct elements from a sequence by using the default equality comparer to compare values." In other words: it compares the elements in the enumerable (which can be an array, or a list, or a dictionary, etc.) and filters out the duplicates, so the result contains all values from the original array only once.

    Input Validation. In practice, program users don't always follow instructions, and you can get a mismatch between what a program expects as input and what it actually gets. Such conditions can cause a program to fail. However, often you can anticipate likely input errors, and, with some extra programming effort, have a program detect and work around them. Suppose, for example, that you're how to check if String input is Integer or not in C#? I have a textbox control in my windows form application and I need to check if the value entered is Integer or string. I can not find any method such as IsNumeric() in C#.

    18/08/2012В В· Hi, Please help me with C code to find the number entered is integer or float????? Thanks in advence. /*To check if a given number is an integer or not*/ #include int main() { float a; printf("Enter the number you wanna check: "); scanf("%f",&a); if(a==(int)a
