A portable hand-held electronic calculator for performing feet, inch, and fraction calculations and for displaying numerical results in feet, inches, and fractions of inches. Values for feet, inches, and fractions of inches can be entered directly without first changing the numbers into a decimal format and complex calculations, such as multiplication, division, addition, subtraction, squares and square roots can be performed directly. A specialized sequential display allows the user to manually enter numeral data in a particular sequence related specifically to the sequence that feet, inches, and fractions are conventionally written and spoken in the construction industry.
