Crate dashu_macros

A macro library for creating big numbers from literals.

See the documentation of each macro for the usage.

Dependency requirement

Due the fact that the macros expand to plain tokens, and proc macro crates can’t re-export types, it’s required to add explicit dependency to the underlying crates when using the macros. Specifically, you need to add the following crates as dependencies to your Cargo.toml:

• For ubig!/static_ubig! and ibig!/static_ibig!: dashu-int
• For fbig! and dbig!: dashu-int, dashu-float
• For rbig!: dashu-int, dashu-ratio

If you are using these macros from the dashu crate, then it’s not necessary to explicitly adding these dependencies, because the related types are re-exported by the dashu crate.

Macros

dbig

Create an arbitrary precision float number (dashu_float::DBig) with base 10 rounding to the nearest.

fbig

Create an arbitrary precision float number (dashu_float::FBig) with base 2 rounding towards zero.

ibig

Create an arbitrary precision signed integer (dashu_int::IBig)

rbig

Create an arbitrary precision rational number (dashu_ratio::RBig or dashu_ratio::Relaxed).

static_dbig

Create an arbitrary precision float number (dashu_float::DBig), with base 10 rounding to the nearest, as a static reference.

static_fbig

Create an arbitrary precision float number (dashu_float::FBig), with base 2 rounding towards zero, as a static reference.

static_ibig

Create an arbitrary precision signed integer (dashu_int::IBig) as a static reference.

static_rbig

Create an arbitrary precision rational number (dashu_ratio::RBig or dashu_ratio::Relaxed) as a static reference.

static_ubig

Create an arbitrary precision unsigned integer (dashu_int::UBig) as a static reference.

ubig

Create an arbitrary precision unsigned integer (dashu_int::UBig)
