So if I use: #include "zmij.h" #include <stdio.h> int main() { char buf[zmij::buffer_size]; zmij::dtoa(1.0, buf); puts(buf); } I get `g++ zmij.cc test.c -o test && ./test` => `0.000000000000001e+15`

  My bad, you are right. The small integer optimization should be switched to a different output method (or disabled since it doesn't provide much value). Thanks for catching this!

    Should be fixed now.

"1.e-01" is for 0.1, not 1.0.

  I assume they meant 1.e+00 That is what Schubfach does

    Yeah, that's what I meant.
