Modify Function
Calculation results are internally obtained in scientific notation
with up to 14 digits for the mantissa. However, since calculation
results are displayed in the form designated by the display
notation and the number of decimal places indicated, the inter-
nal calculation result may differ from that shown in the display.
By using the modify function, the internal value is converted to
match that of the display, so that the displayed value can be
used without change in subsequent operations.

Solver Function
The x value can be found that reduces an entered equation to “0”.
• This function uses Newton's method to obtain an approxima-
tion. Depending on the function (e.g. periodic) or start value,
an error may occur (Error 2) due to there being no
convergence to the solution for the equation.
• The value obtained by this function may include a margin of
error. If it is larger than acceptable, recalculate the solution
after changing ‘Start’ and dx values.
• Change the ‘Start’ value (e.g. to a negative value) or dx value
(e.g. to a smaller value) if:
• no solution can be found (Error 2).
• more than two solutions appear to be possible (e.g. a cubic
equation).
• to improve the arithmetic precision.
• The calculation result is automatically stored in the X memory.
