Real Part: Also denoted as
Variants of $\map \Re z$ for the real part of a complex number $z$ are:


 * $\mathrm {Re} \set z$
 * $\map {\mathscr R} z$
 * $\map {\mathrm {re} } z$
 * $\map {\mathfrak R} z$
 * $\map {\mathbf R} z$ or $\mathbf R z$

While the fraktur font is falling out of fashion, because of its cumbersome appearance and difficulty to render in longhand, its use for this application is conveniently unambiguous.
