Float to string

[mjscott]

I'm looking for a float to string like that in sprintf, except I want to be able to place the format string in a ram buffer. Any thoughts?

Unfortunately, the answer will be 'write your own'. Be prepared for just how large this will become though. The 'reason' the standard command is limited to a constant string, is that this allows a lot of the code to be omitted from the used version. A 'general purpose' float to string, with variables as inputs, will be _big_...
There are some printf code examples on the web, which could be modified, but if you don't need the full abilities of a printf, then a much simpler conversion could be used. For instance, I did one that just allowed the number of displayed digits to be set in a variable. This was relatively simple to do, just involving outputing the value digit by digit using a division, adding a decimal point when the remainder when fractional, and stopping after the variable number of digits.
