Re: [sage-support] sagetex - result with comma as decimal separator

Hello,
As a belgian french speaking user of sagetex and a mathematics & physics 
teacher I needed a "french formated" output.
Indeed,with the above method, the output is then a string. This anoying if you 
have more complex output (scientific notation, ...)

If you are interested, here is my personnal solution:
It goes through "sagestr":

  #   Pour adapter la sortie LaTeX de sage aux conventions francaises.
  def numprint(x):
     x = latex(x)
     x = str(x)
     x = x.replace('.', ',\!').replace('\\times','\, \ldotp')
     x = sage.misc.latex.LatexExpr(x)
     return x
       
  #and use \sagestr{numprint(x))}


I join a demo:
demoGenInt000.pdf and demoGenInt000.tex

If you find this useful, thank you to let me know.
(I am new to the group and made a mistake yesterday, sorry for those of you who 
received this message more than once.)
