Round down to 2 decimal in python

Round down to 2 decimal in python

To round down to a specific number of decimal places in Python, you can use the math.floor() function from the math module. This function rounds a number down to the nearest integer. Here's how you can round down to 2 decimal places:

import math

number = 3.14159
rounded_down = math.floor(number * 100) / 100  # Multiply by 100, round down, then divide by 100
print(rounded_down)  # Output: 3.14

In this example, the number 3.14159 is rounded down to two decimal places using the formula math.floor(number * 100) / 100. The number is first multiplied by 100 to shift the decimal point, then rounded down using math.floor(), and finally divided by 100 to restore the original scale.

You can create a function to round down any number to a specified number of decimal places:

def round_down(number, decimals):
    factor = 10 ** decimals
    return math.floor(number * factor) / factor

number = 3.14159
rounded_down = round_down(number, 2)  # Round down to 2 decimal places
print(rounded_down)  # Output: 3.14

Keep in mind that the result of rounding down might not be exactly what you expect due to floating-point precision limitations. If you require more precise decimal arithmetic, consider using the decimal module.

Examples

    value = 3.4567
rounded_value = int(value * 100) / 100.0
print(rounded_value)

      import math

value = 3.4567
rounded_value = math.floor(value * 100) / 100.0
print(rounded_value)

        import math

value = 3.4567
rounded_value = math.floor(value * 100) / 100.0
print(rounded_value)

          value = 3.4567
rounded_value = int(value * 100) / 100.0
print(rounded_value)

            value = 3.4567
rounded_value = int(value * 100) / 100.0
print(rounded_value)

              value = 3.4567
rounded_value = int(value * 100) / 100.0
print(rounded_value)

                value = 3.4567
rounded_value = int(value * 100) / 100.0
print(rounded_value)

                  value = 3.4567
rounded_value = int(value * 100) / 100.0
print(rounded_value)

                    value = 3.4567
rounded_value = int(value * 100) / 100.0
print(rounded_value)
