Interestingly some numbers can be perfectly represented in Base 10, but not in Base 2. An example is one-tenth (in Base 10, this is 0.1; in Base 2 this is a repeating decimal. Suppose we set both f and g to one-tenth using the statements below. f = 0.1; g = 0.1; Answer the following questions. For each, mark the best answer. Which will be closer to the actual value of one-tenth? f g Which can hold higher values? f g Which takes more memory? f g When using real values I should always use type double, to be safe. True False
Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.

In computer science, floating-point numbers are a crucial aspect of numerical computing. Both Java and C provide two main types for storing real numbers: float and double. These types follow the IEEE 754 standard for floating-point arithmetic, specifying how many bits are to be used for the sign, exponent, and mantissa for each. This answer will explore the differences between float and double in relation to representing the value one-tenth (0.1), covering aspects such as accuracy, value range, and memory consumption. Moreover, it will address the common notion that one should always use double for real values to be on the safe side.
