Hi folks,
running Mathematica 4.0.1 I am stuck with the following problem:
Input:
Print["-1,97E-04"];
Print[StringReplace["-1,97E-04", {"," -> "."}]];
Print[ToExpression[StringReplace["-1,97E-04", {"," -> "."}]]];
Output:
-1,97E-04
-1.97E-04
-9.35502
Can somebody explain this to me? Why does the ToExpression Function
not make the decimal -1.97E-04 out of the String "-1.97E-04". What in
the hell is going wrong (-9.35502->"Where does this number come
from?") and what can be done to circumvent the ToExpression function.
I am greatful for any kind of comments on this problem/bug.
regards
Nils
