Numeric Operations
Arithmetic Operations
Arithmetic operations are fundamental operations that manipulate numeric values. They include addition, subtraction, multiplication, division, and modulo. Here's an example in Python:
a = 10
b = 3
addition = a + b # 13
subtraction = a - b # 7
multiplication = a * b # 30
division = a / b # 3.3333333333333335
modulo = a % b # 1

Comparison Operations
Comparison operations are used to compare two numeric values, returning a boolean result. They include less than, less than or equal to, greater than, greater than or equal to, equal, and not equal. Here's an example in JavaScript:
let a = 10;
let b = 3;
let lessThan = a < b; // false
let lessThanOrEqual = a <= b; // false
let greaterThan = a > b; // true
let greaterThanOrEqual = a >= b; // true
let equal = a === b; // false
let notEqual = a !== b; // true

Conversion Operations
Conversion operations are used to change the data type of a numeric value. They include type casting and explicit conversion functions. Here's an example in C++:
#include <iostream>
#include <string>
int main() {
int a = 10;
double b = 3.14;
double c = static_cast<double>(a); // 10.0
int d = static_cast<int>(b); // 3
std::string e = std::to_string(a); // "10"
std::cout << c << ", " << d << ", " << e << std::endl;
return 0;
}

Logical Operations
Logical operations are used to perform operations on boolean values, such as AND, OR, and NOT. Here's an example in Java:
boolean a = true;
boolean b = false;
boolean and = a && b; // false
boolean or = a || b; // true
boolean notA = !a; // false
boolean notB = !b; // true

Complex Type Operations
Complex Number Operations
Complex number operations involve manipulation of complex numbers, which have real and imaginary parts. Here's an example using Python's complex type:
a = complex(2, 3) # 2 + 3j
b = complex(1, -1) # 1 - 1j
addition = a + b # 3 + 2j
subtraction = a - b # 1 + 4j
multiplication = a * b # 5 + 1j
division = a / b # 0.5 + 1.5j

Matrix Operations
Matrix operations involve manipulation of matrices, such as addition, subtraction, and multiplication. Here's an example using Python's NumPy library:
import numpy as np
A = np.array([[1, 2], [3, 4]])
B = np.array([[5, 6], [7, 8]])
addition = np.add(A, B) # [[6, 8], [10, 12]]
subtraction = np.subtract(A, B) # [[-4, -4], [-4, -4]]
multiplication = np.dot(A, B) # [[19, 22], [43, 50]]

FAQs
What are the differences between arithmetic, comparison, and conversion operations?
Arithmetic operations manipulate numeric values, such as addition and subtraction. Comparison operations compare two numeric values, returning a boolean result. Conversion operations change the data type of a numeric value, such as type casting.
Can I perform logical operations on non-boolean values?
In some programming languages, you can perform logical operations on non-boolean values. These languages may interpret non-boolean values as "truthy" or "falsy" depending on their content. For example, in JavaScript, an empty string is considered "falsy," while a non-empty string is considered "truthy."
How do I work with complex numbers in languages that don't have built-in support?
You can use external libraries or create your own complex number class to handle complex numbers in languages that don't have built-in support. For example, in C++, you can use the std::complex class from the <complex> header.
What are some common use cases for matrix operations?
Matrix operations are commonly used in computer graphics, image processing, machine learning, and linear algebra.
Can I perform bitwise operations on numeric values?
Bitwise operations manipulate individual bits in a binary representation of a numeric value. Most programming languages support bitwise operations, such as AND, OR, XOR, and NOT, as well as bit shifting.
