Python supports three main types of numbers: integers, floating-point numbers, and complex numbers. Each type has its own characteristics and uses. Python also provides various built-in functions and operators to perform mathematical operations.<\/p>\n\n\n\n

Integer (int)<\/h2>\n\n\n\n

Integers are whole numbers, both positive and negative, without a decimal point.<\/p>\n\n\n\n

<\/p>\n\n\n\n

x<\/code> is a positive integer, and y<\/code> is a negative integer.<\/p>\n\n\n\n

x = 10\ny = -3\n<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Floating-Point (float)<\/h2>\n\n\n\n
Floating-point numbers are real numbers with a decimal point. They can also be represented in scientific notation.<\/p>\n\n\n\n
<\/p>\n\n\n\n
a<\/code> and b<\/code> are floating-point numbers, while c<\/code> is a floating-point number represented in scientific notation.<\/p>\n\n\n\n
a = 3.14\nb = -2.5\nc = 1.5e2  # Equivalent to 1.5 * 10^2 or 150.0\n<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Complex (complex)<\/h2>\n\n\n\n
Complex numbers have a real part and an imaginary part, and they are written in the form a + bj<\/code>.<\/p>\n\n\n\n
<\/p>\n\n\n\n
d is a complex number with a real part 2<\/code> and an imaginary part 3j<\/code>. e<\/code> is another complex number created using the complex()<\/code> function.<\/p>\n\n\n\n
d = 2 + 3j\ne = complex(1, -1)\n<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Basic Mathematical Operations<\/strong><\/h2>\n\n\n\n
1. Addition (+)<\/strong><\/p>\n\n\n\n
pythonresult = x + a # Adds an integer and a float<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
2. Subtraction (-)<\/strong><\/p>\n\n\n\n
pythonresult = x - y # Subtracts one integer from another<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
3. Multiplication (<\/strong>*)<\/p>\n\n\n\n
result = a * b  # Multiplies two floats<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
4. Division (\/)<\/strong><\/p>\n\n\n\n
result = x \/ y  # Divides one integer by another<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
5. Floor Division (\/\/)<\/strong><\/p>\n\n\n\n
result = x \/\/ y  # Performs floor division<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
6. Modulus (%)<\/strong><\/p>\n\n\n\n
result = x % y  # Returns the remainder of the division<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
7. Exponentiation(**)<\/strong><\/p>\n\n\n\n
result = x ** 2  # Raises x to the power of 2<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
Built-in Mathematical Functions<\/strong><\/h2>\n\n\n\n
Python provides several built-in functions for mathematical operations.<\/p>\n\n\n\n
1. abs()<\/strong><\/p>\n\n\n\n
absolute_value = abs(-5)  # Returns 5<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
2. round()<\/strong><\/p>\n\n\n\n
rounded_value = round(3.14159, 2)  # Returns 3.14<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
3. pow()<\/strong><\/p>\n\n\n\n
power = pow(2, 3)  # Returns 8<\/pre><\/div>\n\n\n\n
<\/p>\n\n\n\n
4. max() and min()<\/strong><\/p>\n\n\n\n
maximum = max(1, 2, 3, 4, 5)  # Returns 5\nminimum = min(1, 2, 3, 4, 5)  # Returns 1<\/pre><\/div>\n\n\n\n
