 Float is a IEEE 754 binary64 value.
 
 A float consists of integer part, fractional part and exponent part. An
-integer part is required, and follows same rule as decimal [integer](#integer)
-. A fractional part is prefixed with a full stop (`U+002E`), and consists of
-one or more decimal digits. An exponent part is prefixed with `e` or `E`, and
-consists of an integer, which follows same rule as decimal [integer](#integer)
-but leading zeros are allowed. Either a fractional part or an exponent part
-are required.

 A float will be expressed by `(i + f) * (10 ** e)` where `i` is an integer
 part, `f` is a fractional part prefixed with `0.` (if eliminated, `f` is 0),
