    en.wikipedia.org/wiki/Significant_figures

    As an illustration, the decimal quantity 12.345 can be expressed with various numbers of significant figures or decimal places. If insufficient precision is available then the number is rounded in some manner to fit the available precision. The following table shows the results for various total precision at two rounding ways (N/A stands for ...

    The Indian numbering system is used in the Indian subcontinent (Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, Sri Lanka) to express large numbers.The terms lakh or 1,00,000 (one hundred thousand, written as 100,000 in Pakistan, and outside the Indian subcontinent) and crore or 1,00,00,000 [1] (ten million, written as 10,000,000 outside the subcontinent) are the most commonly used terms ...

  6. Image sensor format - Wikipedia

    Sizes are often expressed as a fraction of an inch, with a one in the numerator, and a decimal number in the denominator. For example, 1/2.5 converts to 2/5 as a simple fraction, or 0.4 as a decimal number. This "inch" system gives a result approximately 1.5 times the length of the diagonal of the sensor.
