FX-603P Simulator is a very precise simulationof the classic FX-603P programmable calculator and all it'saccessories. This simulation is not a toy but but a full featuressimulations of almost functionality of the original calculator andit can be used as a full featured and fully programmable scientificcalculator.Used as a calculator the FX-603P simulator will exceed most othercalculator available. The FX-603P simulator supports allarithmetic, trigonometric, logarithmic, hyperbolic, statisticalfunctions and all alphanumeric display options of the originalcalculator.And last not least the FX-603P simulator is fully programmable. Youcan write up to 20 programs, using 110 registers.With the build in FA-6 cassette interface simulation you can saveand load programs and data to your thump drive for later use. Orprintout results with the FP-10 thermal printer simulation and thencopy / paste them to other applications.Do visit our FX-603P website or blog where you can download theoriginal Manual of the Calculator. Remember that theMarket-Comments have no answer function and I can't help you if youpost there.SUPPORTED ANDROID FUNCTIONS:• Calculation results can be copies to the clipboard.• Can be installed on the SD-Card.• Participates in Androids build in backup and restore.• Tablet compatible.• Extra Printer for Tablets.BASIC FEATURES:• Specification:Arithmetic operations (addition, subtraction,multiplication and division, raising to power and root – alljudging the priority of operations) negative umbers, exponent, 33parentheses at 11 levels and constant operations.• Scientific Functions: Trigonometric and inverse trigonometricfunctions (with angle in degrees, radians or gradients), hyperbolicand inverse hyperbolic functions, logarithmic and exponentialfunctions. inverse.
