2. 31. According to C99 standard,

**long long**is an integer type which is at least 64-bit wide. There are two integer 64-bit types specified:**long long**int and unsigned**long long**int. So, yes, this is the biggest integer type specified by C language standard (C99 version).People also ask, what is long long in Java?

**long**: The

**long**data type is a 64-bit two's complement integer. The signed

**long**has a minimum value of -2

^{63}and a maximum value of 2

^{63}-1. In

**Java**SE 8 and later, you can use the

**long**data type to represent an unsigned 64-bit

**long**, which has a minimum value of 0 and a maximum value of 2

^{64}-1.

Subsequently, question is, is long 32 bit or 64 bit?

What is the

**bit**size of**long**on**64**-**bit**Windows? Windows:**long**and int remain**32**-**bit**in length, and special new data types are defined for**64**-**bit**integers.What is difference between == equals () and compareTo () method?

**compareTo**: Compares two strings lexicographically.

**equals**: Compares this string to the specified object.

**compareTo**compares two strings by their characters (at same index) and returns an integer (positive or negative) accordingly.

**equals()**checks if two objects are the same or not and returns a boolean.

Is float always 32 bit?

Specifically, the Cray XMP computers had a 64-

**bit floating**point type as their single precision**float**. An integer can still be**32 bits**on a 64**bit**machine. A**float**is then still a**float**too: usually we say it is**32 bits**, but everyone is free to deviate from it.
