Eric Smith added the comment: Unless and until we implement 'd' exponents, we should add a test to make sure they don't work. That they ever worked on any platform was a surprise. -- Eric. -- title: reading scientific notation using d instead of e on max osx -> reading scientific not

Mark Dickinson added the comment: Sorry, I'm -1 on this: outside Fortran, using 'E' for the exponent marker seems to be near universal. It just doesn't seem worth adding the extra complication to the Python code, or going through all the various places that expect an 'e' (float literals in

ricitron added the comment: I am running python 2.5.4. While it works on linux and windows, it does not work on mac. Fortran doubles are output using the D notation. If I am importing a large amount of data, I would rather not do a search and replace every time before reading in the data.

Mark Dickinson added the comment: Out of curiosity, where are your data coming from? For Python, this seems like a needless complication. It should be simple enough to replace the 'D's with 'E's prior to passing the strings to float. I notice that some varieties of Lisp and Scheme use 's', '

New submission from ricitron : I would like to be able to read in data that uses scientific notation with a D instead of an E. This is possible on windows and other builds, but not on Mac OSX. example: float('1.23D+04') Traceback (most recent call last): File "", line 1, in ValueError: inv
