# Extended floating point (f80)

A 80-bit floating point type that provides greater precision than the basic floating-point formats.
It is an x86 exclusive and it's mainly used to minimize roundoff and overflow errors in smaller floating point types.
For non-compatible targets, the "f80" type is an alias of "f64"<br>
