Any number that includes a decimal portion is a floating-point value. For exam-

ple, 1.0 has a decimal part, so it’s a floating-point value. Many people get 

confused about whole numbers and floating-point numbers, but the difference 

is easy to remember. If you see a decimal in the number, it’s a floating-point 

value. Python stores floating-point values in the 

float

 data type. The maximum 

value that a floating point variable can contain is ±1.7976931348623157 × 10

308

 

and the minimum value that a floating point variable can contain is 

±2.2250738585072014 × 10

–308

 on most platforms.
