AMOS Basic V134 ´&RD AMOSPro_Calc was designed to be run from the AMOSPro Editor as an %RB accessory or from the user menu. There are a few hidden features&RD which I feel should be documented although most functions are self R explanatory.R&RD 1. There is a hidden Dragbar located above the calculator display &RD which may be used to drag the calculator up or down the editor R screen.R)RJ 2. The two small buttons on either side of the calculator (near the top)'RF are to quit the calculator, alternatively pressing the Escape keyR has the same effect. R&RD 3. It is possible to convert numbers between Decimal, Hexadecimal (RH and Binary simply by clicking the appropriate buttons Dec/Hex/Bin, (RH although if a number too large to be displayed in binary is entered(RH in either Decimal or Hexadecimal mode and then converted to Binary (RH an Error message will be displayed and only a C/CE will remove it. %RB In Hexadecimal mode the extra small keys near the = key will (RH become active allowing digits 0-9 and A-F to be entered. In Binary R2 mode only the digits 0 and 1 may be entered. R&RD 4. The fix function can be used to display numbers with between 0 'RF and 11 digits after the decimal point. At the moment this occurs &RD without any rounding either up or down and simply displays the 'RF chosen number of digits. It is possible to alter fix up and down R6 on the displayed number without loss of accuracy.$R@ To use fix click the FIX button and enter a number between &RD 0 and 11, when the = key is pressed the display will be reset. 'RF You can go back to floating point decimal format by clicking the R FD key. R&RD 5. Due to a shortage of braincells parenthesis () has not yet been'RF implemented which does limit its usefulness as a full scientific R calculator.RRRR$ Brief Rundown of the various keys.RR ( Does nothing yetR ) Does nothing yetR" Sin give sin of displayed numberR* Asn give arcsin of displayed number R" Cos give cos of displayed numberR& Acs give arccos of displayed number R" Tan give tan of displayed numberR& Atn give arctan of displayed number R0 Log give common logarithm of displayed number R4 10x give common antilogarithm of displayed number !R: Square root button gives square root of displayed numberR" x2 squares the displayed number R2 1/x gives the reciprocal of the displayed numberR, Fd change to floating point decimal formatR( !x gives factorial of displayed number$R@ Int give integer portion of displayed number (not reversible) %RB Frc give fractional portion of displayed number (not reversible) R8 Fix allows the number of displayed digits to be fixed R Deg select degree modeR Rad select radian modeR Dec select decimal output R Hex select hexadecimal output R Bin select binary outputR M store display in memory R MR recall memory to display R0 MR+ add contents of memory to current display R6 MR- subtract contents of memory from current display%RB X-Y swap order of operation.
