Re: [PHP] PHP Brainteasers 2011
what's the scope? I have some brain-teasing functions i've been working on, but they are far from bulletproof, but here is an example function float_int($significand) { $sign = ($significand<0) ? true : false; $significand = abs($significand); $drep = (decbin( (int) $significand)); $frep = ""; for($i = 0; $i <= 22; $i++) { $significand = ($significand - (int) $significand)*2; if($significand == 0) break; $frep .= ($significand >= 1) ? "1" : "0"; } $significand = preg_replace("/^0*1/", "", $drep.$frep); $significand = (strlen($significand) < 23) ? str_pad($significand, 23, "0") : substr($significand, 0, 23); if($drep) { $exponent = decbin(126+strlen($drep)); } else { $tmp = preg_split('/1/', $drep.$frep, 2, PREG_SPLIT_OFFSET_CAPTURE); $exponent = decbin((-$tmp[1][1])+127); } $f = bindec($exponent.$significand); return (!$sign) ? $f : $f^0x; } I guess the function name and variable names will offer some assistance in determining what this does, but i think its an interesting brain-bender, not very useful, because its pretty slow, but still :) -- Alex -- -- The trouble with programmers is that you can never tell what a programmer is doing until it’s too late. ~Seymour Cray On Fri, May 20, 2011 at 12:49 PM, Steve Staples wrote: > Just wondering if anyone has done anything for this?
