abstract struct Float
Overview
Float is the base type of all floating point numbers.
There are two floating point types, Float32
and Float64
,
which correspond to the binary32
and binary64
types defined by IEEE.
A floating point literal is an optional +
or -
sign, followed by
a sequence of numbers or underscores, followed by a dot,
followed by numbers or underscores, followed by an optional exponent suffix,
followed by an optional type suffix. If no suffix is present, the literal's type is Float64
.
1.0 # Float64
1.0_f32 # Float32
1_f32 # Float32
1e10 # Float64
1.5e10 # Float64
1.5e-7 # Float64
+1.3 # Float64
-0.5 # Float64
The underscore _
before the suffix is optional.
Underscores can be used to make some numbers more readable:
1_000_000.111_111 # better than 1000000.111111
