this website has a simple calculator,
http://www.sengpielaudio.com/calculator-soundpath.htm

when i click [calculate] gives NaN Error in Latest Opera for Windows 8.1x64
but the same website works OK, with Internet Explorer 11.0.9600

error also happens in Chrome 72 and FireFox 65.

i have OSX Sierra, and EDGE for Android & EDGE for W10x32 but im lazy.
