Python Floating-Point Numbers - Scientific Notation - Overflow Error - Programming Examples
A floating-point number is a number with a decimal. Ex: 3.14, or -123.5. float is a data type for floating-point numbers.
A floating-point literal is the number being used in your python code. Ex: weight = 145.2
Use scientific notation for huge numbers such as 1.87x1045. Ex: 1.87e45. The e stands for exponent.
The value range for floating-point numbers is from 2.3x10-308 to 1.8x10308. range. Assigning a variable outside this range causes an OverflowError. Overflow happens when a value is too large to be stored in the memory allocated by the interpreter.
When printing floating-point numbers, use f string formatting to specify the number of decimals to print out.
Ex: print(f’{math.pi:.3f}')
