[Matplotlib-users] nicely formatted exponential in title

[Neal B. <ndb...@gm...>]

I tried:

plt.title (r'$\omega=%s$' % omega), where omega=-1e-5.  The title says:

omega=-1e-05

with the 'e' in italics, and the whole thing generally ugly.

What I'd like to see is what TeX would do for $1 \times 10^{5}$.

I know mpl already can nicely format numbers for axis.  Can I somehow use that
mechanism to nicely format numbers in my title (or other places)?

Have you tried latex_float() as suggested here ?

def latex_float(f):
     float_str = "{0:.2g}".format(f)
     if "e" in float_str:
         base, exponent = float_str.split("e")
         return r"{0} \times 10^{{{1}}}".format(base, int(exponent))
     else:
         return float_str

title (r'$\omega=%s$' % latex_float(omega))
