 Numbers - Decimal Fractions - Contents

Decimal fractions are common fractions converted into decimal form by dividing the numerator by the denominator. In the decimal system of numeration the results yield a decimal fraction. A decimal fraction consists of an integer part, then a decimal point, and then a decimal part which contains the tenths, hundredths, thousandths and so forth. The ratio of any two integers always is a rational number. A rational number converts to a decimal fraction that has a finite number of digits or an infinitely repeating decimal part. The decimal part of an irrational number cannot be expressed by a finite number or a series of repeating numbers, instead it is a continuous stream of random, nonrepeating numbers.
