2.43 is in decimal form so the purpose of this question is far from clear. There are two decimal forms that are equivalent. One is 2.4300... with as many 0s as you wish. However, you need to be aware that these trailing 0s imply increased precision which may not be justified. Another equivalent form is 2.4299... recurring.
