Dear Mike,
Thanks a lot for that, this looks very promising. However, after
making the suggested change, the behaviour of latex() did not change.
Do I need to restart sage for the changes to take effect?
dummy._latex_?? reflects the changes made, but the 0s are still there
when I latex(dummy).
dummy = 0.6;dummy
0.600000000000000
dummy._latex_??
File: /Users/sschym/Programs/sage/devel/sage/sage/rings/real_mpfr.pyx
Source Code (starting at line 959):
def _latex_(self):
s = self.str()
parts = s.split('e')
if len(parts) > 1:
# scientific notation
if parts[1][0] == '+':
parts[1] = parts[1][1:]
s = "%s \\times 10^{%s}" % (str(parts[0]).rstrip('0'),
parts[1])
else:
s = s.rstrip('0')
return s
latex(dummy)
0.600000000000000
Cheers
Stan
