Float to string with more digits?
Is there a more accurate way to do a float and or double to string than... to!string(float); As that seems to limit itself to 6 digits.

Use std.string.format or std.format.formattedWrite. std.format contains a description of the various format specifiers. You'll probably want something like %.12f, which formats a floating point number with 12 digits of precision. that did it, thanks, :)

What about std.format.format(%.12f, myFloat)?
Or, if you like:
string floatToString(F)(F f)
if (isFloatingPoint!F)
{
// Extract as many digits as are available for this
// type.
return std.format.format(%.*f, F.dig, f);
}

Re: Float to string with more digits?
Just to clarify what i needed was... %.8g or %.7e Significant digits, or fixed width scientific form. I needed more significant digits. %.8f controls how many digits to print after the decimal point, which is not the same thing.
