If the argument is integer then the result is integer.
Math roof java.
The class math contains methods for performing basic numeric operations such as the elementary exponential logarithm square root and trigonometric functions.
If the argument value is less than zero but greater than 1 0 then.
Math e having a value as 2 718281828459045.
It cannot be chosen or reset by the user.
If the argument is nan or an infinity or positive zero or negative zero then the result is the same as the argument.
Hence the math class java provides these two constants as double fields.
This relaxation permits better performing implementations.
The java lang math ceil returns the double value that is greater than or equal to the argument and is equal to the nearest mathematical integer.
The implementation selects the initial seed to the random number generation algorithm.
Java ceil method the method ceil gives the smallest integer that is greater than or equal to the argument.
The ceil method rounds a number upwards to the nearest integer and returns the result.
If the passed argument is an integer the value will not be rounded.
Unlike some of the numeric methods of class strictmath all implementations of the equivalent functions of class math are not defined to return the bit for bit same results.
The java lang math floor is used to find the largest integer value which is less than or equal to the argument and is equal to the mathematical integer of a double value.
A let us have a look at the table below that shows us the basic methods and its description.
The java lang math ceil double a returns the smallest closest to negative infinity double value that is greater than or equal to the argument and is equal to a mathematical integer.
Special cases if the argument value is already equal to a mathematical integer then the result is the same as the argument.
Math pi having a value as 3 141592653589793.
If the argument is nan or an infinity or positive zero or negative zero then the result is the same as the argument.
