# Typeset Re(a+ib)

How to typeset the "Re" of Re(a+ib) correctly inside an equation in latex? I tried using \mathcal and \mathbb but it does not give me the typical rounded R I already saw in other documents...

Any help? Thanks in advance!

Use $\Re(a + ib)$
Might \mathfrak{Re} be what you're looking for?
