    Here the 'IEEE 754 double value' resulting of the 15 bit figure is 3.330560653658221E-15, which is rounded by Excel for the 'user interface' to 15 digits 3.33056065365822E-15, and then displayed with 30 decimals digits gets one 'fake zero' added, thus the 'binary' and 'decimal' values in the sample are identical only in display, the values ...

    A formula can then be created that says "Total Sales = Unit Price times Unit Sales". Then if "Total Sales" view is added to the workbook, the totals would automatically appear there, because the sheet "knows" that is what the formula is for. But the real power of Improv did not become clear until work had already started on the project.

    Note the formula on the dot-matrix line above and the answer on the seven-segment line below, as well as the arrow keys allowing the entry to be reviewed and edited. This calculator program has accepted input in infix notation, and returned the answer , ¯. Here the comma is a decimal separator.

  5. Round-off error - Wikipedia

    en.wikipedia.org/wiki/Round-off_error

    In computing, a roundoff error, [1] also called rounding error, [2] is the difference between the result produced by a given algorithm using exact arithmetic and the result produced by the same algorithm using finite-precision, rounded arithmetic. [3]

  6. Integer overflow - Wikipedia

    en.wikipedia.org/wiki/Integer_overflow

    The register width of a processor determines the range of values that can be represented in its registers. Though the vast majority of computers can perform multiple-precision arithmetic on operands in memory, allowing numbers to be arbitrarily long and overflow to be avoided, the register width limits the sizes of numbers that can be operated on (e.g., added or subtracted) using a single ...

    It also works well for batch upload, where a file input may be rejected and a set of messages sent back to the input source for why the data is rejected. Another form of enforcement action involves automatically changing the data and saving a conformant version instead of the original version. This is most suitable for cosmetic change.

  9. Formula calculator - Wikipedia

    en.wikipedia.org/wiki/Formula_calculator

    Once a formula is entered, a formula calculator follows the above rules to produce the final result by automatically: Analysing the formula and breaking it down into its constituent parts, such as operators, numbers and parentheses. Finding both operands of each binary operator. Working out the values of these operands.
