Module Percent.Format

A Format.t tells Percent.format how to render a floating-point value as a string, like a printf conversion specification.

For example:

format (Format.exponent ~precision) = sprintf "%.e" precision

The _E naming suffix in Format values is mnenomic of a capital E (rather than e) being used in floating-point exponent notation.

Here is the documentation of the floating-point conversion specifications from the OCaml manual:

type t
val sexp_of_t : t -> Ppx_sexp_conv_lib.Sexp.t
val exponent : precision:Base.Int.t -> t

sprintf "%.*e" precision

val exponent_E : precision:Base.Int.t -> t

sprintf "%.*E" precision

val decimal : precision:Base.Int.t -> t

sprintf "%.*f" precision

val ocaml : t

sprintf "%F"

val compact : precision:Base.Int.t -> t

sprintf "%.*g" precision

val compact_E : precision:Base.Int.t -> t

sprintf "%.*G" precision

val hex : precision:Base.Int.t -> t

sprintf "%.*h" precision

val hex_E : precision:Base.Int.t -> t

sprintf "%.*H" precision
