Struct swc_ecma_ast::Number
source · pub struct Number {
pub span: Span,
pub value: f64,
pub raw: Option<Atom>,
}
Expand description
A numeric literal.
Creation
If you are creating a numeric literal with a dummy span, please use
literal.into()
, instead of creating this struct directly.
All of Box<Expr>
, Expr
, Lit
, Number
implements From<64>
and
From<usize>
.
Fields§
§span: Span
§value: f64
Note: This should not be NaN
. Use crate::Ident to represent NaN.
If you store NaN
in this field, a hash map will behave strangely.
raw: Option<Atom>
Use None
value only for transformations to avoid recalculate
characters in number literal
