what // FLT_EPSILON == 0.01 equal(4.999, 5); // true 4.999 == 5; // false am i missing?

FLT_EPSILON is not 0.01, it's 0.00000011920929. But it's impossible to have a number that's 0.00000011920929 less than 5.0, or 0.00000011920929 more than 5.0, because the floats with enough magnitude to represent 5 are spaced further apart than that. Only numbers with magnitude In other words, the only 32-bit float that's within ±0.00000011920929 of 5.0 is 5.0 itself.

#include "pretty.h" void print_int(int value){ println(value); } int main (int argc, string argv[]) { long value = 23849234723748234; print_int(value); } How is this strongly typed? $ cc test.c -o test && ./test -1411401334 And to be clear, weak vs strong isn't a boolean property but a spectrum, but would be hard to argue with a straight face than C is a strongly typed language.

C is likely the only example of a programming language that is clearly statically typed while at the same time being weakly typed. For a reason: as your example shows, it's a really bad idea (but understandable for a language from the 60's).

"indefinitely" might be a better name. (But I think loop is indeed a better name.)

Added in commit ef510ca!

Oh you're right, thanks for the explanation! Gotta research now where the 0.00000011920929 number comes from...

It's the distance between 1.0 and the next representable float.

It claims to be a scripting language but you still have to compile the programs. Boo! Add CINT ( https://root.cern.ch/root/html534/guides/users-guide/CINT.ht... ) and you can have instantaneous execution and even a REPL!

Given the idea behind this repo is to cause pain, why not add a shebang to your file [0] to make it executable. I saw a blog post a long time ago that went into the details of how ./foo worked, and how it executed an elf file. You could register `.c` programs in the same way to be compiled and run?
