(Casio) Colour Power Graphic Calculator
64KB Memory (CFX9850GC PLUS)
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, CFX-9850GC+ performs financial and business functions such as Time-Value-of-Money, simple and compound interest, cash flows, and amortization.
CFX9850GC PLUS also performs conversions and calculations for cost/sell/margin, days, and bonds.
