Shorthand numeric conversions.

Contents

Installation

This package is registered in METADATA.jl and so can be installed using Pkg.add

Pkg.add("NumericSuffixes")

Public Interface

NumericSuffixes — Module.

Provides the @suffix macro for generating shorthand numeric conversion suffixes.

Examples

x = 1i8        # Convert `1` to `Int8`.
y = 3u32       # Convert `3` to `UInt32`.
z = (x + y)r16 # Convert `4` to `Float16`.

Default Suffixes

16 suffixes are provided by default:

  • i8 --> Int8

  • i16 --> Int16

  • i32 --> Int32

  • i64 --> Int64

  • i128 --> Int128

  • u8 --> UInt8

  • u16 --> UInt16

  • u32 --> UInt32

  • u64 --> UInt64

  • u128 --> UInt128

  • r16 --> Float16

  • r32 --> Float32

  • r64 --> Float64

  • c32 --> Complex32

  • c64 --> Complex64

  • c128 --> Complex128

Additional user defined suffixes can be made using the @suffix macro.

source
NumericSuffixes.@suffix — Macro.

Generate a new numeric suffix named n which converts numbers to type T.

Signature

@suffix n T

Examples

@suffix i8 Int8

x = 1i8
typeof(x) == Int8

More complex conversions can be made using anonymous function syntax:

@suffix t16 x -> trunc(Int16, x)

x = 1.2t16
typeof(x) == Int16
