Typically since you only have 1 decimal place you don't extend it.
\n" ); document.write( "If you have more decimal places, you can round up.
\n" ); document.write( "So as an example,
\n" ); document.write( "\"23.1837\" to the nearest thousandth would be
\n" ); document.write( "\"23.184\"
\n" ); document.write( "However, 549.5 does not equal 549.500 because now you're implying that you have that much precision in your measurement where you may not really have it. Like if I was measure my height with a tape measure I could say my height was 76 1/2 inches.
\n" ); document.write( "That doesn't mean my height is 76.500 inches because my tape measure doesn't have a precision down to 0.001.
\n" ); document.write( "
