The java lang math sqrt returns the square root of a value of type double passed to it as argument.

Java root function.

Syntax double sqrt double d parameters. The basic syntax of the math sqrt in java programming language to find the square root is as shown below. This method returns the square root of the argument. If the argument is positive infinity this method will return positive infinity.

The following java sqrt function will accept positive double value as an argument and returns the square root of the specified expression or value. Calculating the nth root in java. Calculating the n th root correctly. Return type is double in order to use in program.

If the argument is positive infinity then the result is positive infinity. The method returns the square root of the argument. If the argument is positive double value this method will return the square root of a given value. The java lang math sqrt double a returns the correctly rounded positive square root of a double value.

If the argument is positive zero or negative zero then the result is the same as the argument. Trying to find the n th root in java using pow is inaccurate in some cases. If the argument is positive or negative zero this method will return the result as zero with same sign. The reason for that is that double numbers can lose.

Here is the detail of parameters d any primitive data type. If the argument is nan or negative then the result is nan. If the argument is nan or less than zero this method will return nan. Static double sqrt double number.

If the argument is positive infinity then the result is positive infinity.
