I have a variable $var and its value is 345.678975 (for example).
How can i format $var to became 345.67.... only two digits after the
point...

Another question... my script is generating a html document and i want to

How can i put the $ symbol? The script interpert it as a variable and i just
want the caracter...

Thanks in advance,
Wagner.
