[2][3] The calculator is available in 6 modes:[4] In this mode, if the result has both real and imaginary parts, an "R↔I" symbol will appear at the top right corner.

For some input data, the sum of squares of values (Σx2), sum of values (Σx), number of data (n), sample standard deviation (xσn-1) and population standard deviation (xσn) can be calculated.

2 The calculator can hold up to 4 programs with a total capacity of 360 bytes.

Unconditional jumps[20] use Goto and Lbl to operate.

When Goto n (where n is an integer in 0-9) is executed, the program will jump to Lbl n. Loops can be created with unconditional jumps.
