•When you try to perform a calculation that causes memory capacity to be exceeded
(Memory ERROR).
•When you use a command that requires an argument, without providing a valid argument
(Argument ERROR).
•When an attempt is made to use an illegal dimension during matrix calculations (Dimension
ERROR).
• When you are in the real mode and an attempt is made to perform a calculation that
produces a complex number solution. Note that “Real” is selected for the Complex Mode
setting on the Setup screen (Non-Real ERROR).
k Memory Capacity
In the Linear input mode, each time you press a key, either one byte or two bytes is used.
Some of the functions that require one byte are: b, c, d, sin, cos, tan, log, In, , and π.
Some of the functions that take up two bytes are d/dx(, Mat, Xmin, If, For, Return, DrawGraph,
SortA(, PxIOn, Sum, and an+1.
For details about the number of bytes required for each function in the Math input mode, see
page 1-3-9.

Basic Calculations
#As you input numeric values or commands,
they appear flush left on the display.
Calculation results, on the other hand, are
displayed flush right.
# The allowable range for both input and output
values is 15 digits for the mantissa and two
digits for the exponent. Internal calculations are
also performed using a 15-digit mantissa and
two-digit exponent.
