Write a program in Java to input three numbers and display the greatest and the smallest of the two numbers.The signum(n) method returns -1, 0, and 1 when n is negative, zero, or positive. Solutions to Unsolved Java Programs Question 1 If argument is float, return type is int, if argument is double, return type is long.Īt mid-point, it returns the integer that is evenĪt mid-point, it returns the higher integer.Ī will have a value of 2 and b will have a value of 3 Rounds off its argument to the nearest mathematical integer and returns its value as an int or long type. So, it’s very likely that we’ll get negative numbers: Random random new Random () int randomWithNextInt random.nextInt () If we use the netxInt invocation with the bound parameter, we’ll get numbers within a range: int randomWintNextIntWithinARange random. Rounds off its argument to the nearest mathematical integer and returns its value as a double type. In this example, b will be assigned the value of 65.0 as it is the largest integer smaller than 65.5. In this example, a will be assigned the value of 66.0 as it is the smallest integer greater than 65.5. Returns the largest double value that is less than or equal to the argument and is equal to a mathematical integer. Returns the smallest double value that is greater than or equal to the argument and is equal to a mathematical integer Distinguish between them with suitable examples Question 1 Both return type and argument is of double data type. Returns the natural logarithm of its argument.
Its return type is same as the type of its arguments.
Returns the absolute value of its argument.
#Math.random java negative or positive generator
Returns the cube root of its argument as a double value. 1 1 asked at 11:31 Reshad 2,570 8 45 86 Add a comment 2 Answers Sorted by: 16 You can use: Random generator new Random () int val 100 - generator.nextInt (201) Or, as JoachimSauer suggested in the comments: int val generator. Its return type is same as the type of its arguments. The getRandomNumber() method uses the Math.random() method to return a positive double value that is greater than or equal to 0.0 and less than 1.0. Returns a positive double value, greater than or equal to 0.0 and less than 1.0. Before using the random() method, we must. It generates only double type random number greater than or equal to 0.0 and less than 1.0. Just plug in the values and simplify: double n 1.0 double range 2 n double value range Math.random () - n You can modify the n value to alter the maximum/minimum value generated, for example if you need random numbers in the range -10, 10) then let n 10.0 Limit is actually 2x the maximum number. Math.round(b) Predict the return data type of the following functions Question 1ĭouble Explain the following functions Question 1 The Java Math class has many methods for different mathematical operations. To find the smaller between two numbers p and q Write down the syntax for the following functions Question 1 Here 66.0 is the smallest mathematical integer greater than 65.5 so it is the output. Math.ceil method returns the smallest double value that is greater than or equal to the argument and is equal to a mathematical integer.
