Basic Calculations

•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).

kMemory 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 1-3-11.

#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.
