10BII User Manual
Calc10BII is a business calculator featuring over 100 built-in functions for business, ﬁnance, mathematics and statistics. Easily calculate loan payments, interest rates, amortization, discounted cash-ﬂow analyses, TVM (loans, savings, and leasing)using a simpliﬁed algebraic entry system. The keyboard and display have been carefully optimized for the iPhone and iPod Touch. Five different keyboard layouts allow you to do much more than a 10BII calculator while maintaining compatibility with the standard.
Time Value of Money- Loans, savings, leases and amortization schedules using both the standard keyboard and a specialized TVMsolver window that displays the contents of all the variables for rapid "what if" solutions to your problems. Interest Conversion- Nominal and effective rates. Cash Flows- Net present value and internal rate of return. Up to 40 cash ﬂows are easily edited and reviewed using the dedicated cash ﬂow editor screen. Entries are added, deleted and modiﬁed in a scrolling display with a touch interfaceunique to the iPhone. Business Percentages- Percent change, markup, and margin calculations. Statistics- Mean, standard deviation, correlation coefﬁcient, and linear regression forecasting, weighted mean. Conversions- 47 world currency rates and over 100 commonly used metric, english and other conversion factors used in ﬁnancial, business, scientiﬁc and engineering calculations. Scientiﬁc- sin, cos,tan, asin, acos, atan plus the hyperbolic trig functions, conversion between rectangular and polar coordinates, conversion between degrees and radians, time functions including h.ms+ and h.ms-, log, ln, 10ˣ, eˣ, yˣ, x root of y, fraction part and integer part. Trig functions can be computed in radians, degrees or gradians.
10BII User Manual
Calc10BIIhas 9 keyboards/ screens. A keyboard is selected by touching the blue key followed by home, tvm, CF, conv, math, stats, depr, prt tape or bond. The orange and blue keys work as shift keys. Touch the orange or blue key once to select shift (a colored halo around the key indicates it is selected). Touch the shift key a second time to cancel the shift. When a shift key is selected, the functionsdisplayed in blue or orange are enabled on the keyboard. For example, touch orange followed by + to execute the square root function. The area at the top of the screen displays a variety of annunciators, the main results line and a secondary results line for functions that return 2 values.
Annunciators Input After touching the input key, the secondary results line displays the input value. PendThe pending annunciator displays the number of pending operations in the display line. Up to 20 operations can be pending. Begin The begin/end annunciator indicates that payments occur at the beginning or end of the a period. Touch this annunciator to alternate between begin and end modes of computation. P/YR This annunciator shows the current setting of the P/YR parameter. Amort The amortannunciator displays immediately after performing the amort function. It displays PER for period, PRIN for principal, INT for interest and BAL for balance. C-FLOW The cash ﬂow annunciator indicates the current cash ﬂow entry number after touching CFj or Nj. Deg In math mode the degree annunciator indicates the angular mode in effect- degrees, radians or gradians. Touch it to change the angular mode....
