EStacks • The unit employs memory blocks, called stacks, for storage of low priority values and commands. There is a 10-level numeric value stack, a 26-level command stack, and a 10-level program subroutine stack. If you execute a formula so complex it exceeds.the amount of stack space available, an error menage appears on the display (Stk ERROR during calculations or Ne ERROR during execution of a program subroutine). Example 2-x ( ( 3 + 4 x (5+4) 3) 5) I x xI xI AAIII Stk ERROR Bytes 26 01 20 O ND Numeric Value Stack C) 02 3 4 5 4 Command Stack x O O *Calculations are performed according to the p iority sequence described on page 56. Once a calculation is executed, it is cleared from the stack. *Storing a complex number takes up two numeric value stack levels. *Storing a two-byte function (page 59) takes up two command stack levels. illValue Input and Output Limitations The allowable range for both input and output values is 10 digits for the mantissa and 2 digits for the exponent. Internally, however, the unit performs calculations using 15 digits for the mantissa and 2 digits for the exponent. Example 3 x 105+7-42857= MIMEO= MIEICIICIEEJECIECI 3E5-7 42857.14286 3E5-7-42857 0.1428571428 -58- •Calculation results that are greater than 1015 (10 billion) or less than 10-2 (0.01)'are automatically displayed in exponential form. - •Values are stored in memory with 15 digits for the mantissa and 2 digits for the exponent. Einput 'Capacity • ' This unit has a 127-byte area for ekecution of calculations. Each time youpress a numeric key or arithmetic operation key, one byte of memory is used In addition, the following functions take up two bytes 'each? •d/dx (, E ( •Mat, Det, Trn (in the MAT Mode) • *ROW, *ROW + , ROW + , Swap (in the PRGM-MAT Mode) •Y, r, Xt, Yt, Sim X, Sim Y, Sim Z, Sim T, Sim U, Sim V, Sim Coef, Ply.

Whenever you input the 121st byte-of any calculation, the cursor changes from "_" to "•" on the display to let you know that you are running out of rnernbry. If you still need to inputmore, you should divide your calculation into two or more parts. Note •As you input numeric values or commands, they appear flush left on the display. Calculation result& on the other hand, are displayed flush right MOvedMwandErrom Exceeding a specified input or calculation range, or attempting an illegal input causes an error message to appear on the display. Further operation of the calculator is impossible while an error message is displayed. The following events cause an error message to appear on the display. *When any result, whether intermediate or final, or any value in memory exceeds ±9.999999999 x 1099 (Ma ERROR) •When an attempt is made to perform a function calculation that exceeds the input range (Ma ERROR) (see page 361) •When an illegal operation is attempted during statistical calcdlations (Ma ERROR) For example, attempting to obtain x or_xon _without data input. •When the capacity of the numeric value stack or command stack is exceeded (Stk ERROR) For example, entering 25 successive followed by 2O3134g. •When an attempt is made to perform a calculation using an illegal formula (Syn ERROR) For example, 5ElEI3EI•When an illegal memory specification is made (Mem ERROR) -59-
