Re^7: [OT: JavaScript] JS remainder operation ('%')

Perl's weirdnesses are sometimes just inherited from it's host language C.

Choroba didn't tell us if C has the same output too, but I remember the strange rules to numify ASCII strings to integers stemming from an atoi routine in C.

use warnings;
say "12x45"+1;

__END__

Argument "12x45" isn't numeric in addition

It's not that Larry came up with all of this on his own.

FWIW I don't think this warning was always there...

> 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; }` [download] Output: `0.140000 0.13999999999999999` [download] `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

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]
