java math log10 method

In java Math class, log10 method is used to get the base 10 logarithm of a double value.

• If the number is equal to 10n for integer n, then the result is n. In particular, if the number is 1.0 (100), then the result is positive zero.
• If the number is NaN or less than zero, then the result is NaN.
• If the number is positive infinity, then the result is positive infinity.
• If the number is positive zero or negative zero, then the result is negative infinity.

		System.out.println(Math.log10(2));
		System.out.println(Math.log10(0));
		System.out.println(Math.log10(3.14));
		System.out.println(Math.log10(1));
