The decimal separator is the comma, in Romanian virgulă. For example, 2.5 is written 2,5 and pronounced doi virgulă cinci. The fractional part is read as a multi-digit number, not by saying each digit independently. For example, 3.14 (written 3,14) is pronounced trei virgulă paisprezece (literally three comma fourteen).
This decimal format can also represent any binary fraction a/2 m, such as 1/8 (0.125) or 17/32 (0.53125). More generally, a rational number a/b, with a and b relatively prime and b positive, can be exactly represented in binary fixed point only if b is a power of 2; and in decimal fixed point only if b has no prime factors other than 2 and/or 5.
Fourteen-segment display. A fourteen-segment display ( FSD) (sometimes referred to as a starburst display or Union Jack display[ 1][ 2]) is a type of display based on 14 segments that can be turned on or off to produce letters and numerals.

Three ways to group the number ten thousand with digit group separators. 1) Space, the internationally recommended thousands separator. 2) Period (or full stop), the thousands separator used in many non-English speaking countries. 3) Comma, the thousands separator used in most English-speaking countries. A decimal separator is a symbol that ...
One such arrangement is 6 7 5 8 4 3 9 2 0 1 from front (6) to back (1). [10] [11] Russian ИH-12A (IN-12A) and ИH-12B (IN-12B) tubes use the number arrangement 3 8 9 4 0 5 7 2 6 1 from front (3) to back (1), with the 5 being an upside down 2. The ИH-12B tubes feature a bottom far left decimal point between the numbers 8 and 3.
Piphilology comprises the creation and use of mnemonic techniques to remember many digits of the mathematical constant π. The word is a play on the word "pi" itself and of the linguistic field of philology . There are many ways to memorize π, including the use of piems (a portmanteau, formed by combining pi and po em ), which are poems that ...
For example, while a fixed-point representation that allocates 8 decimal digits and 2 decimal places can represent the numbers 123456.78, 8765.43, 123.00, and so on, a floating-point representation with 8 decimal digits could also represent 1.2345678, 1234567.8, 0.000012345678, 12345678000000000, and so on.
Decimalisation or decimalization (see spelling differences) is the conversion of a system of currency or of weights and measures to units related by powers of 10 . Most countries have decimalised their currencies, converting them from non-decimal sub-units to a decimal system, with one basic currency unit and sub-units that are to a power of 10 ...
