What is JavaScript's highest integer value that a number can go to without losing precision?
(21 answers)
Closed 8 years ago.
I have this in java:
int minimo = Integer.MAX_VALUE;
how would it look in javascript? Is there an equivalent of n"integer" in javascript?
var minimo = Integer.MAX_VALUE;
?
JavaScript has only one number type Number. It automatically switches between floats and integers as needed.
Use Number.MAX_SAFE_INTEGER to get the max integer value and Number.MAX_VALUE to get the max float value.
For me these are 9007199254740991 and 1.7976931348623157e+308

How can I assign value of light year in meters in java to datatype, it seems it is too long.
For example:- 9,460,730,777,119,564 is value in mtrs for 1 light year
The Long datatype in standard java 2^63-1 digits, so the speed of light in meters should fit
You can use Long for it.
Long lightYearsInMeters = new Long("9460730777119564");
System.out.println(lightYearsInMeters);

If I have a java float and I want to increment/decrement it by the minumim possible value how can I determine that value? I mean it is a difference if the value of the float is already a very large number like 3.4028235E38 or a very small number like 1.4E-45. In the first case to note any difference I need to subtract a far lager number as I would need to add to the second case right?

I am doing simple calculation in java. Expected result is 51.3348 but what I am getting is 51.0, here is my calculation
float percent = (7819140000l-3805200000l)*100/7819140000l;
Is that problem with datatype? How can I resolve this to get value as 51.3348
Thanks in Advance
add an f to one of the values:
float percent = (7819140000l-3805200000l)*100f/7819140000l;
if yiu do not do it, Java will make a devision by long values

Int division: Why is the result of 1/3 == 0?
(19 answers)
Closed 6 years ago.
Eg: I divide manually 8/3 = 2.666666.
When I divide in Java, I've got 8/3 = 2.0 instead.
How can I get the answer to display 2.667 or 2.67?
Thank you.
You are doing integer division hence result is integer
you need to do ((double)8)/3 to get desired result

I am trying to convert 10000000000000000000000000000000 to BigInteger.
But it is not converting.
My code is
BigInteger number = BigInteger.valueOf(10000000000000000000000000000000);
It is showing The literal 10000000000000000000000000000000 of type int is out of range.
Is there any way to convert this number as I have to use this number as integer in my programme?
The whole point of BigInteger is to support numbers long and int cannot so you can't use those. What you can do is use a String.
BigInteger bi = new BigInteger("10000000000000000000000000000000"):
