The decimal numeration system is based on base 10. Each position in a number has a value that is a power of 10. A decimal point separates the nonnegative powers of 10 (10^{0}=1, 10^{1}=10, 10^{2}=100, 10^{3}=1,000, etc.) on the left from the negative exponents (10^{1}=1/10, 10^{2}=1/100, 10^{3}=1/1000, etc.) on the right.
Decimal Number  Written as a Fraction  Written in Terms of Place Value 

4.1  4 1/10  4 plus 1 tenth 
12.34  12 34/100  1 ten plus 2 ones plus 3 tenths and 4 hundredths 
0.01  1/100  1 hundredth 
The following chart shows the value of each place in a decimal number (written as a simple number, as an exponent, and in English):
100,000 = 10^{5} hundred thousands 
10,000 = 10^{4} ten thousands 
1,000 = 10^{3} thousands 
100 = 10^{2} hundreds 
10 = 10^{1} tens 
1 = 10^{0} ones 
decimal point  1/10 = 10^{1} tenths 
1/100 = 10^{2} hundredths 
1/1,000 = 10^{3} thousandths 
1/10,000 = 10^{4} ten thousandths
