What is difference between int and char?

The difference is the size in byte of the variable, and from there the different values the variable can hold. A char is required to accept all values between 0 and 127 (included). An int is required to be at least a 16 bits signed word, and to accept all values between -32767 and 32767.

What is difference between double and decimal?

The fundamental difference is that the double is a base 2 fraction, whereas a decimal is a base 10 fraction. double stores the number 0.5 as 0.1, 1 as 1.0, 1.25 as 1.01, 1.875 as 1.111, etc. decimal stores 0.1 as 0.1, 0.2 as 0.2, etc.

What is the difference between char and varchar?

Char vs Varchar The basic difference between Char and Varchar is that: char stores only fixed-length character string data types whereas varchar stores variable-length string where an upper limit of length is specified.

What is the difference between int i and float I?

Integers and floats are two different kinds of numerical data. An integer (more commonly called an int) is a number without a decimal point. A float is a floating-point number, which means it is a number that has a decimal place. Floats are used when more precision is needed.

What is the difference between == and =? Quizlet?

What is the difference between a float and a double quizlet?

3.7 Q2: What is the DIFFERENCE between a float and a double? a. a. double variables store integers and float variables store floating-point numbers. b. b. double variables store numbers with smaller magnitude and coarser detail.

What is difference between long and double?

The main difference between long and double in Java is that long is a data type that stores 64 bit two’s complement integer while double is a data type that stores double prevision 64 bit IEEE 754 floating point. In brief, long is an integral type whereas double is a floating point type.
