Custom Text Formatting (Previously: Getting long results in a program)

CAS could help with large integers, but for small floating-point values, E notation would also appear (for floating-point calculations, CAS internally operates with precision up to the 15th decimal place, but presents a maximum of 12). In such a case, this can be handled manually without CAS by first converting the given value to text, and then adding the appropriate number of zeros to the front or back and adjusting the decimal point accordingly.
