Re^8: [OT: JavaScript] JS remainder operation ('%')

> Choroba didn't tell us if C has the same output too

Well, it kind of has, but it's a bit tricky as you have to explicitly use printf.

#include <stdio.h>

int main(int argc, char** argv) {
    printf("%f\n",    1.4/10);
    printf("%.17f\n", 1.4/10);
    return 0;
}

Output:

0.140000
0.13999999999999999

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

Thanks. My guess is that stringification of floats happens with `sprintf` `"%.15g"` Though the default max-precision for format `g` seems to be 6, both in Perl and C. š I started testing this theory, but it's a bit cumbersome inside termux. :) Cheers Rolf _{(addicted to the Perl Programming Language :) see Wikisyntax for the Monastery} š) According to online docs: maximum-width https://en.cppreference.com/w/c/io/fprintf	[reply] [d/l] [select]
