Decimal point handling and Rounding:  

Automatic round-off/cut-off in multiplication and division,
(fixed decimal point with accumulation of decimal place selector 0 to 5).

Constant function:  

Constant function speeds up calculation work: 
Simply make entry, then touch the
[X]-key twice and the number becomes constant multiplier or constant multiplicand.
Also touch the
[(dvivision)]-key twice, and the number becomes constant divisor. 
The [T2/K]-key can be used as a constant in chain multiplication and/or chain division.

Extra features/remarks:  

The AS-C is so designed that two automatic accumulations can be made without any special operation, which CASIO called the double total method.
The total of products and/or quotients can be obtained by the
[T1]-key and multipliers and/or divisors by [T2/K]-key.
0peration: 
Addition, Subtraction, Multiplication, Division, Square, Chain multiplication, Chain Division, Power calculation, Calculation with a constant, Product/quotient sum and difference, Automatic accumulation of products/quotients showing individual product/quotient in single and chain multiplication,
Automatic accumulation of products/quotients in multiplication/division with a constant,
Accumulation of sums anddifferences , Accumulation of multiplier or divisor.
Keyboard with Reed-switches.
Rather unique 'Landscape'-design, just as the:
CASIO: ASA, CASIO: ASB, CASIO: ASL
Almost identical to model
