possible to not use scientific notation #65

Open pinggit opened 4 years ago

pinggit commented 4 years ago

I'd like to see 1234567890 instead of 1.23456789e9. is it possible?

You can adjust g:crunch_precision, higher than the default of 6 to something like 15 or 20, and you might get the effect you like. It doesn't disable scientific notation, but it won't be displayed as often.

e.g. put this in your .vimrc

let g:crunch_precision = 15

@pinggit did this work for you?

hi, thanks for the update. I'll test it out and feedback the result.

it does not work.

12345678 = 1.2345678e7
12345678 + 12345678 = 2.4691356e7

after I set this to 15: g:crunch_precision #15

This does indeed not work. In autoload/crunch.vim:vim_eval():659, printf() is called w/ %g, which as per :help printf will print a floating point number, as %f or %e depending on value (e.g. possibly employing scientific notation) as opposed to %f which will print a floating point number as 12.23, inf, -inf or nan. Hence, I propose that a new tunable (e.g. g:crunch_scientific_notation) be introduced to select between %g, %e, or %f, addressing this issue.
