Step-by-Step Guide to Using the Decimal Calculator

Step 1: Enter a Decimal Number

Begin by locating the input field labeled Decimal Number. Enter a decimal number in this field. Ensure that the number conforms to the required validation, which means the number should be a decimal and you may need to enter it in increments specified by the step value of 1e-06.

Step 2: Select an Operation

Next, proceed to the input field labeled Operation. This is a dropdown selection menu. Choose one of the following operations based on what you want to do with your decimal number:

  • Round to nearest whole number: Rounds the number to the nearest integer.
  • Floor (round down): Rounds the number down to the nearest integer.
  • Ceiling (round up): Rounds the number up to the nearest integer.
  • Truncate decimal places: Removes decimal places to the specified number.

Note that choosing an operation is mandatory as per the validation requirements.

Step 3: Specify Decimal Places

If your selected operation involves specifying decimal places (such as truncate), you will need to enter the number of decimal places in the field labeled Decimal Places. This input requires a number between 0 and 10. Ensure the value you enter meets the validation requirements, meaning it should be a whole number between 0 and 10. This step is crucial for operations involving rounding or truncation.

Step 4: View the Results

Once you’ve provided all the necessary inputs, the calculator will process the information and provide results in the following fields:

  • Rounded Result: Displays the result of the selected operation on your decimal number, formatted to 10 decimal places if applicable.
  • Fractional Part: Shows the fractional part of your decimal number, calculated as the original decimal number minus the floored value, displayed to 10 decimal places.
  • Whole Part: Shows the whole part of your decimal number after applying the floor function, displayed as an integer (without decimals).

By following these steps, you can efficiently use the Decimal Calculator to perform various operations on decimal numbers and observe detailed results.
