Claims

[Scope of utility model registration request]

In a small electronic calculator that has a plurality of hexary modes and performs calculations using the hexary numbers in each mode, means for holding the hexary mode of the calculator, numerical input means, and key means for instructing conversion to a desired hexary number. and a base number conversion means for converting the numerical value inputted from the numerical value input means from the base number of the mode held by the holding means to the base number instructed by the key means in accordance with the instruction of the key means. A compact electronic calculator with a decimal conversion function, characterized in that unless the mode of the holding means is changed, only the conversion from the decimal number in the mode to another decimal number is performed.
