short

Consider following program: #include <stdio.h> int main() { short a=9; //printf("%hi\n",a); printf("%d",a); // LINE 6 } According to this the format specifier for short type (signed) is %hi Is the short type variable always gets promoted automatically to int before performing any operation on it? Is it undefined behavior , If I use %d format specifier to print the value of variable in this program? I compiled it using gcc -Wall -Wextra -WFormat options but still compiler isn't showing any single warning. Why? printf("%hi\n", a); a is promoted to int as per the rules of default argument

Closed . This question needs details or clarity . It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post . Closed 5 years ago . I have this sine wave which generates floating point values (e.g. 0.37885) but I want them as shorts. Direct casting with short gives me a value of 0. so what is the solution? Can anyone tell me how to do it - ideally without loss of precision - or minimal loss of precision if this is all that is possible? public static short floatToShort(float x) { if (x < Short.MIN_VALUE) { return Short.MIN

So I've looked around for how to convert a string to a short and found a lot on how to convert a string to an integer. I would leave a question as a comment on those threads, but I don't have enough reputation. So, what I want to do is convert a string to a short, because the number should never go above three or below zero and shorts save memory (as far as I'm aware). To be clear, I'm not referring to ASCII codes. Another thing I want to be able to do is to check if the conversion of the string to the short fails, because I'll be using a string which consists of a users input. I know I can do

I have: int a = 2147483647; short b = (short)a; and I get b = -1 whereas I expect int32 to be converted to int16 ( short ). I expect to see some value and not -1 . Please someone help me with this. Your int A is larger than the size of short. When you convert A to short, you get a 1 in the left most bit, which is going to indicate that it is a negative number. Since you're getting -1, I suppose you're getting 1s in all 16 bits, which is going to give you -2^15 + 2^14 + 2^13... + 2^0, which will give you -1. In short (no pun intended), you can't convert the integer to a short if it is too large

I want to generate a random number of type short exactly like there is a function for integer type called Random.nextInt(134116). How can I achieve it? There is no Random.nextShort() method, so you could use short s = (short) Random.nextInt(Short.MAX_VALUE + 1); The +1 is because the method returns a number up to the number specified (exclusive). See here This will generate numbers from 0 to Short.MAX_VALUE inclusive (negative numbers were not requested by the OP) Java shorts are included in the -32 768 → +32 767 interval. why wouldn't you perform a Random.nextInt(65536) - 32768 and cast the

K&R states, that if either operand is an int the other operand will be converted to int . Of course, that is only after all the other rules (like long double , float , unsigned int etc.) have been followed. By that logic, char would be converted to int , if the other operand was an int . But what if the highest integer type in an operation is a short ? Now, obviously I don't need to explicitly convert a char to a bigger integer, but I do wonder, does ANSI-C handle implicit conversion between char and short under the hood? K&R does not say anything about that. Say, I have the following lines of

I am printing Toast message in my application to show notification but i want to know value of Toast.LENGTH_LONG and Toast.LENGTH_SHORT. What other values i can use. Can anyone tell me what is the value of these two variables? George Baker There is another question that answers what you are looking for. The answers are: private static final int LONG_DELAY = 3500; // 3.5 seconds private static final int SHORT_DELAY = 2000; // 2 seconds This was courtesy of FeelGood. You can find the whole thread below. Can an Android Toast be longer than Toast.LENGTH_LONG? Hope this helps. There are only these
