A few weeks ago @Per shared the intention to work on a library that may suit your needs, if your type will be a subtype of AbstractFloat (but it may not be the case):

My idea is to write a package AbstractFloatMath (working title) of pure-Julia routines for common mathematical functions (sin, log, sqrt, …) that will take AbstractFloat arguments, i.e. work with any user defined type that is <: AbstractFloat. For a new floating-point type, it will be enough to i…
