This, truly, is a most sophisticated calculating device and well worth the price when considered as a long-term investment. It is mechanically quite sound and will provide many years of reliable work. The hard, slide-on case will protect the keys and screen from damage and keep the calculator in a clean and presentable condition.
In addition to all the great features of the CS-CFX9850G, CFX-9850GC PLUS offers list based, one and two variable statistics.
It also performs linear, median-median, quadratic, polynomic, cubic, quartic, logarithmic, exponential, power, logistic, and sinusoidal regressions.
On top of that, the CFX-9850GC+ performs financial and business functions such as Time-Value-for-Money, simple and compound interest, cash flows, and amortization.
CFX9850GC PLUS also performs conversions and calculations for cost/sell/margin, days, and bonds.
