Multi-Function Ruler With 8 Digits Display Calculator
The multi-function ruler with 8 digits display calculator is a mini and portable calculator with a clear LED screen. It's easy to read the numbers at a glance and has sensitive buttons that respond quickly when pressed. It uses 1 piece regular cell power for efficient usage and has auto power-off feature. Its compact and lightweight design makes it ideal for daily use at school, office and home.
The calculator includes a ruler and is suitable for student and professional use. It is made of high quality ABS plastic material and has a length of 15cm. Its multi-functional 2 in 1 design makes it useful for basic math operations as well as measuring.
Mastery Connect allows you to create presets for frequently used measurement scales for the Ruler and Count tools. These are set by choosing Image > Analysis > Set Measurement Scale. If no preset is set, the default measurement scale of 1 pixel = 1 pixel will be used.
A slide rule has several scales, each of which can be used to perform a specific function. For example, one of the scales has graduations labeled with precomputed outputs of various mathematical functions, such as powers of 2, allowing you to solve equations by aligning the two rulers and reading the result from a position in between the labeled graduations. Other scales can be used to calculate logarithms, trigonometric functions, and other types of calculations.
Unlike ordinary rulers, slide rules let you add and subtract. However, in the heyday of slide rules, this was considered a trivial task that could be done in your head or on paper. The most important feature of a slide rule is the ability to multiply and divide.
In the pixel measurement scale presets, you can specify a value for a linear distance between the center of the ruler and the edge of the selection, and a number to use as the basis for calculating area and perimeter. The number of decimal places in the result depends on the size of the selected region and the number of data points in the selection. You can also create a custom data point preset for the Ruler tool by selecting a combination of measurement values for which you want to receive an answer, and clicking Custom.
