Format numbers

Precision & precision type: The number of significant digits or decimal places to be used in the output. If the precision type is decimal places, the notation will be automatically set to Decimal. You can set the number of significant digits to be shown when results have decimal numbers. The valid values are from 1 to 15, which is the maximum. Like the round() command, the last digit is rounded to nearest with half-up tie-breaking, just like the round() command.

Precision
Significant figures: 5	Significant figures: 10
Decimal places: 5	Decimal places: 10

Output notation: Sets the output notation to be scientific or decimal or asks the kernel to decide in every case automatically. Note this does not apply to integers, and all input forms are supported regardless of this option.

Output notation
Decimal	Scientific

Decimal, digit group, and list separators: No symbol can be used as a separator of two different things simultaneously. These options affect both input and output. Changing them automatically updates both inputs and outputs to work with the new settings.
