  2. Numeric precision in Microsoft Excel - Wikipedia

    en.wikipedia.org/wiki/Numeric_precision_in...

    Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...

  3. Volume correction factor - Wikipedia

    en.wikipedia.org/wiki/Volume_Correction_Factor

    That is, observed temperatures above 60 °F (or the base temperature used) typically correlate with a correction factor below "1", while temperatures below 60 °F correlate with a factor above "1". This concept lies in the basis for the kinetic theory of matter and thermal expansion of matter , which states as the temperature of a substance ...

  4. Variable pathlength cell - Wikipedia

    en.wikipedia.org/wiki/Variable_pathlength_cell

    Variable pathlength absorption spectroscopy uses a determined slope to calculate concentration. As stated above this is a product of the molar absorptivity and the concentration. Since the actual absorbance value is taken at many data points at equal intervals, background subtraction is generally unnecessary.

    Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).

  6. End-systolic volume - Wikipedia

    en.wikipedia.org/wiki/End-systolic_volume

    End-systolic volume (ESV) is the volume of blood in a ventricle at the end of contraction, or systole, and the beginning of filling, or diastole. ESV is the lowest volume of blood in the ventricle at any point in the cardiac cycle. The main factors that affect the end-systolic volume are afterload and the contractility of the heart.

  7. Plus–minus sign - Wikipedia

    en.wikipedia.org/wiki/Plus–minus_sign

    When the standard presumption that the plus-or-minus signs all take on the same value of +1 or all −1 is not true, then the line of text that immediately follows the equation must contain a brief description of the actual connection, if any, most often of the form "where the ‘±’ signs are independent" or similar.

  8. Subtraction - Wikipedia

    en.wikipedia.org/wiki/Subtraction

    The Austrian method often encourages the student to mentally use the addition table in reverse. In the example above, rather than adding 1 to 5, getting 6, and subtracting that from 7, the student is asked to consider what number, when increased by 1, and 5 is added to it, makes 7.

  9. English Standard Version - Wikipedia

    en.wikipedia.org/wiki/English_Standard_Version

    The ESV translation committee states that "the goal of the ESV is to render literally what is in the original." [ 17 ] The committee expands on this position in stating that, although the ESV avoids using gender-neutral language (for the purpose of preserving contextual meaning found in the original text), the translation does utilize gender ...
