View Replies View RelatedHow To Find If BigInteger Is Square
Jul 3, 2014I have a program i m not sure how to implement :
(Square numbers) Find the first ten square numbers that are greater than Long.MAX_VALUE . A square number is a number in the form of n 2 . For example, 4, 9, and 16 are square numbers. Find an efficient approach to run your program fast.
I found two ways of solving this but i think both are way inefficient :
-A square number can be divided in lesser square numbers :
what's the square of 36 ? 36 is 2 * 3 * 2 * 3 => 4 * 9 => square is 2 * 3
-second option is to estimate a number and increase it or decrease it based on how close that number * number is to the BigInteger starting number , as as it gets closer the delta gets smaller until it gets to 1

Handling Very Large Numbers Without Using BigInteger?
Dec 9, 2014I am calculating an exponent without using BigInteger. However, I find that using long is not enough to handle my code. Is there a way to handle large numbers without using BigInteger?

int base = 3;

Conversion Char To Double Value
Mar 31, 2015I need to understand the java Conversion.
I have a char[] containing ASCII characters that need to be converted into int value and double value.
The int value are always stored in 1 char size like 'j'. I extracted it succesffully by converting the char in a ascii bytearray and then used: Integer.parseInt(sb.toString().replace("0x", ""), 16);
How can I get the Value as double when i used the char[] with size 2 or 4 ?
Example : final char[] charValue = { 'u', ' ', '}','+' }; what is the associate Double value ?
Example : final char[] charValue = { 'T', ' ' }; what is the associate Double value ?
Example : final char[] charValue = { 'T', ' ' }; what is the associate int value ?

Type Conversion And Most Significant Bit
Apr 14, 2014If I type
long z = 0xDeadCafe;
System.out.print(z);
I get a negative number as a result.
But if I append an L to the hex number:
long z = 0xDeadCafeL;
the resulting number is a positive one.
What the difference is between those two lines:
long z = 0xDeadCafeL;
and
long z = 0xDeadCafe;
(same as above, but without the suffix L).
If I don't append the L, is the msb (most significant bit) somehow still carried over to the resulting long variable and in the latter case, where I append an L, it is not and instead the value is filled up with 32 leading zeros (4 Byte difference between int and long)?
