  2. Windows Calculator - Wikipedia

    en.wikipedia.org/wiki/Windows_Calculator

    A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.

  3. Surface metrology - Wikipedia

    en.wikipedia.org/wiki/Surface_metrology

    Surface metrology is the measurement of small-scale features on surfaces, and is a branch of metrology.Surface primary form, surface fractality, and surface finish (including surface roughness) are the parameters most commonly associated with the field.

  4. HP 35s - Wikipedia

    en.wikipedia.org/wiki/HP_35s

    The HP 35s (F2215A) is a Hewlett-Packard non-graphing programmable scientific calculator. Although it is a successor to the HP 33s, it was introduced to commemorate the 35th anniversary of the HP-35, Hewlett-Packard's first pocket calculator (and the world's first pocket scientific calculator). HP also released a limited production anniversary ...

  5. Surface roughness - Wikipedia

    en.wikipedia.org/wiki/Surface_roughness

    Different capital letters imply that the formula was applied to a different profile. For example, R a {\displaystyle Ra} is the arithmetic average of the roughness profile, P a {\displaystyle Pa} is the arithmetic average of the unfiltered raw profile, and S a {\displaystyle Sa} is the arithmetic average of the 3D roughness.

    A formula editor is a computer program that is used to typeset mathematical formulas and mathematical expressions. Formula editors typically serve two purposes: They allow word processing and publication of technical content either for print publication, or to generate raster images for web pages or screen presentations.

  8. Programmable calculator - Wikipedia

    en.wikipedia.org/wiki/Programmable_calculator

    Some calculators run a subset of Fortran 77 called Mini-Fortran; the compiler is on the calculator so connecting to a PC to put programs onto the machine is not needed. The OnCalc C Compiler for the Casio fx-9860 series is now available. The Sharp PC G850V pocket computer has an onboard C compiler in addition to an assembler and a Basic ...

    en.wikipedia.org/wiki/Gauge_block

    The minimum conditions for wringability are a surface finish of 1 microinch (0.025 μm) AA or better, and a flatness of at least 5 μin (0.13 μm). [4] There is a formal test to measure wringability. First, the block is prepared for wringing using the standard process.
