Struct gds21::GdsFloat64

pub struct GdsFloat64;

GDSII’s Home-Grown Floating-Point Format

Incredibly, GDSII is old enough to have its own float-format, like most computers did before IEEE754.

The GdsFloat64 struct is not used as a data-store, but largely a namespace for the encode and decode operations to and from IEEE754 double-precision format.

Implementations

impl GdsFloat64

pub fn decode(val: u64) -> f64

Decode GDSII’s eight-byte representation, stored as a u64, to IEEE (and Rust)-compatible f64

pub fn encode(val: f64) -> u64

Encode f64 to GDSII’s eight bytes, stored as u64.
