Floating point number is real numbers with decimal point (.)or fractional part. It can be positive or negative.<\/div>\n
<\/div>\n
Example:<\/div>\n
5678.90

0.99<\/div>\n

>>> z = -1.234<\/div>\n
>>> type(z)<\/div>\n
<class ‘float’><\/div>\n<\/blockquote>\n<\/div>\n
<\/div>\n
<\/div>\n
Let’s do arithmetic:<\/div>\n
<\/div>\n
\n
\n
>>> x = 8+8.1<\/div>\n
>>> print (x)<\/div>\n
16.1<\/div>\n
>>> print (type(x))<\/div>\n
<class ‘float’><\/div>\n<\/blockquote>\n
<\/div>\n<\/div>\n
\n

Some key notes:<\/p>\n

1. numbers separated with underscore can consider a valid float as long has decimal point<\/p>\n<\/div>\n

<\/div>\n
\n
\n
>>> x = 66_77_88.3_21<\/div>\n
>>> type (x)<\/div>\n
<class ‘float’><\/div>\n<\/blockquote>\n<\/div>\n
2. real numbers\u00a0 with a fractional part represented by scientific notation e or E, or those floating numbers that exceeded the maximum size (1.8 * 10^308), it will be referred as “infinity” or “inf”<\/div>\n
<\/div>\n
\n
\n
>>> 1.8e308<\/div>\n
inf<\/div>\n
>>> x = 1.8e308<\/div>\n
>>> print (x)<\/div>\n
inf<\/div>\n
>>> type (x)<\/div>\n
<class ‘float’><\/div>\n<\/blockquote>\n<\/div>\n
\n
\n
>>> 0.4e9<\/div>\n
400000000.0<\/div>\n
>>> x = 0.4e9<\/div>\n
>>> type (x)<\/div>\n
<class ‘float’><\/div>\n<\/blockquote>\n<\/div>\n
<\/div>\n
3. there’s a function float() to convert string into float class.<\/div>\n

>>> float (x)<\/div>\n
