#21628 [NEW]: decimal numbers without decimal places

From: czapel@go2.pl Operating system: SuSE Linux 8.0 PHP version: 4.2.2 PHP Bug Type: *Math Functions Bug description: decimal numbers without decimal places I have some unexplicable problem, when I try to perform any mathematical operation. This is my example script: <? echo microtime()."<br>"; $a=1.121212; $b=2.999999; echo gettype($a)."<br>"; echo gettype($b)."<br>"; echo bcmul($a,bcmul($b,$b,10),10)."<br>"; $c=$a*$b*$b; echo $c; ?> To make sure that browser doesn't read from cache I put microtime. The problem is that sometimes as a result I get number with decimal places (and this is ok), but sometimes I get just integers as a result, in this case it is 4. Maybe somebody has already heart about that. I have no idea, how should I lose this problem. Please, help me.
