Decimal time is the representation of the time of day using units which are decimally related, such as 10 hours, 100 minutes and 100 seconds. Learn about the history and systems of decimal clocks in different cultures, such as Egypt, China, France and Japan.
Metric time is the measure of time intervals using the metric system, with the second as the base unit. Learn about the origin, evolution and usage of metric time units, such as kiloseconds, milliseconds and decicés.
Learn how Excel calculates numbers with limited accuracy and precision due to rounding, truncation, binary storage, and cancellation. See examples of errors and differences between decimal and binary representations of numbers.
Learn how to write numbers in scientific notation, a way of expressing large or small numbers as m × 10 n, where n is an integer and m is a nonzero real number. Find out the history, advantages, and applications of scientific notation in science, math, and engineering.
The "decimal" data type of the C# and Python programming languages, and the decimal formats of the IEEE 754-2008 standard, are designed to avoid the problems of binary floating-point representations when applied to human-entered exact decimal values, and make the arithmetic always behave as expected when numbers are printed in decimal.
This scheme can also be referred to as Simple Binary-Coded Decimal (SBCD) or BCD 8421, and is the most common encoding. [12] Others include the so-called "4221" and "7421" encoding – named after the weighting used for the bits – and "Excess-3". [13]
Metrication is the process of converting to the metric system of measurement, which is used by 95% of the world's population. Learn about the origins, challenges and progress of metrication in different countries and regions, from France to the United Kingdom to the United States.
A timesheet is a method for recording the amount of a worker's time spent on each job. It can be used for payroll, billing, project management, costing and performance evaluation. Learn about the history, types and benefits of timesheets.
