7- 4)  Fraction calculations

Total of integer, numerator and denominator must be 

within 10 digits (includes division marks).

A fraction can be transferred to the memory.

When a fraction is extracted, the answer is displayed 

as a decimal.

A press of  AB/C  key after the  =   key converts the 

fraction answer to the decimal scale.
