Decimal and, only the best mathematicians were able to multiply or divide large numbers. These difficulties were completely solved with the introduction of the Hindu–Arabic numeral system for representing integers. This system has been extended to represent some non-integer numbers, called "decimal fractions" or "decimal numbers" for forming the "decimal numeral system". For writing numbers, the decimal system uses ten decimal digits, a decimal mark, and, for negative numbers, a minus sign "−". The decimal digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9; the decimal separator is the dot "" in many countries (including English speaking ones),
Binary integer decimal Binary integer decimal The IEEE 754-2008 standard includes an encoding format for decimal floating point numbers in which the significand and the exponent (and the payloads of NaNs) can be encoded in two ways, referred to in the draft as binary encoding and "decimal encoding". Both formats break a number down into a sign bit "s", an exponent "q" (between "q" and "q"), and a "p"-digit significand "c" (between 0 and 10−1). The value encoded is (−1)×10×"c". In both formats the range of possible values is identical, but they differ in how the significand "c" is represented. In the decimal
