[#absl-HighPrecision-0b7]
= xref:absl.adoc[absl]::HighPrecision
:relfileprefix: ../
:mrdocs:

Converts a `double` to a string which, if passed to `absl::SimpleAtod`, would produce the exact same original floating point value (except in case of NaN; all NaNs are considered the same value).

== Synopsis

Declared in `<absl/strings/str_cat.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
/* implementation-defined */
HighPrecision(double d);
----

== Description

Tries to keep the string short but it's not guaranteed to be as short as possible. `HighPrecision` is considerably slower than the default formatting, so only use it if you need the string to convert back to the same floating‐point value.

== Return Value

A buffer holding the round‐trippable string representation.

== Parameters

[cols="1,4"]
