The main problem with converting a number with a comma and decimal to a float is that the number may not be correctly rounded. This can cause unexpected results when trying to perform calculations or perform comparisons.
number = "1,000.00"
float(number.replace(",", ""))
The first line creates a string variable called “number” and assigns it the value “1,000.00”. The second line converts the string variable “number” into a float variable by removing the comma characters and returning the result as a float.
Decimal numbers
In Python, decimal numbers are represented by the decimal module. To create a decimal number, you use the Decimal() function. For example, to create a number that is equal to 10.5, you would use the Decimal() function and pass in the value 10.5 as an argument.
To convert a decimal number to a string representation, you can use the str() function. For example, if you wanted to print out the string “10.5”, you would use the str() function and pass in the value 10.5 as an argument.
Float type
Float type is a data type in Python that stores real numbers. It can be used for variables that store numeric values, such as age, salary, and temperature.
