Did the Romans use fractions?

Math Forum: Ask Dr. Math FAQ: Roman Numerals
The Romans didn't have a standard way to write fractions using their numerals. Instead, they just wrote out the word for the fraction: for example, two-sevenths was "duae septimae" and three-eighths was "tres octavae." The Romans did not have a word for every imaginable fraction: how often do you need to say thirty-three seventieths? If necessary, they would probably have said something like, "thirty-three seventieth parts," or "triginta tres septuagensimae partes.

How did the Romans use math?

Math Forum: Ask Dr. Math FAQ: Roman Numerals
Unlike the ancient Greeks, the Romans weren't particularly interested in "pure" math, such as theorems about abstract geometry. They used their mathematics for more practical purposes, such as building roads, bridges, and temples out of stone, keeping accounts, and supplying their armies. People went on using Roman numerals for hundreds of years after the Roman empire fell. See similar questions...

How did the Romans number days?

The Christian Calendar
The Romans didn't number the days sequentially from 1. Instead they had three fixed points in each month: Kalendae'' (or ''Calendae''), which was the first day of the month. ''Idus'', which was the 13th day of January, February, April, June, August, September, November, and December, or the 15th day of March, May, July, or October. ''Nonae'', which was the 9th day before Idus (counting Idus itself as the 1st day). See similar questions...

What do the fractions in the Manual Flash settings represent?

EVOLT E-510 > Frequently Asked Questions
The photographer has the option of using different power settings in the Manual Flash mode to balance the fill flash with available light exposure. You may have seen TV clips of celebrity and news photographers using fill-flash outdoors. Fill-flash throws a little extra light into shadows to "open" them up to get a more pleasing image. You can also use this technique in landscape and travel photography to show a little more detail in the shadows of foreground subjects. See similar questions...

Does MySQL 5.1 have a NOW() function with fractions of seconds?

Appendix A. Frequently Asked Questions About MySQL 5.1
No. This is on the MySQL roadmap as a "rolling feature". This means that it is not a flagship feature, but will be implemented, development time permitting. Specific customer demand may change this scheduling. However, MySQL does parse time strings with a fractional component. See Section 11.3.2, "The TIME Type". Yes. MySQL is fully multi-threaded, and will make use of multiple CPUs, provided that the operating system supports them. See similar questions...

How do the fractions modes work?

Digi-Fence Frequently Asked Questions
First, select which fractions mode to work in: 16ths, 32nds, or 64ths; this allows you to use whichever units you are already comfortable with. When working in 16ths or 32nds mode, bars appear over the displayed reading to indicate an extra 1/64"; this is especially helpful when you want to cut a part Heavy (long). The display will only show the next fractional value when it is actually reached, thereby preventing a part being cut too short (Ex: 0.249 will NOT show 1/4"). See similar questions...

Is it possible to give rating fractions such as 3.5?

Appraisal Smart and Smart360 User FAQs
The AS System does not support a 0.5 rating fraction (or 10-point rating scale for that matter), as it is generally very difficult to distinguish between, say, a 7- and an 8-rating, and could, therefore, easily be cause for conflict. Additionally, having a more distinct difference between one rating level and the next, forces the parties to make a decision one way or the other (based on actual performance) without opting for a "cop-out" middle ground.
