Do Math Object Reals allow for more control over when scientific notation kicks in?
We have a few exercises that are meant to actually teach scientific notation, so we want say 0.000002 to show on screen as is, and not auto-convert to 2e-6 or 2E-6. Can we make this happen without resorting to constructing a string?
I've looked for a context flag to control this, but if it is out there I am missing it.

Yes. You can set a format string in the Context that tells MathObjects how to format its Real numbers. See

for details. It is essentially an
You might also want to consider the contextScientificNotation.pl macro file, which implements a Context designed for requiring student answers in scientific notation. It has some handy controls for the number of digits in input and output.

sprint() format string, with the default being %g, which uses scientific notation when the magnitude is sufficiently big or sufficiently small, but you can change it to a "%f"-style format instead to prevent scientific notation.You might also want to consider the contextScientificNotation.pl macro file, which implements a Context designed for requiring student answers in scientific notation.
