var fDesc=new Array(); fDesc[0] = "FNA is a multi-function scientific calculator and unit conversion utility. Four modes of operation (statistics, trigonomety, base-n, and unit conversion). Convert units of Acceleration, Angle, Area, Density, Energy, Force, Fuel Efficiency, Length, Mass/Weight, Power, Pressure, Speed, Temperature, Time, Torque and Volume. Perform complex mathematical calculations using such operations as factorial, gamma, combinations, permutations, logarithms, standard and hyperbolic trigonometric functions, and base-n conversions and logical operations. Store and recall even between sessions with 26 separate memory registers. Special calculations include heat index, wind chill and days between dates. Built-in references now include Periodic Table of Elements with extensive chemical data, drop-down conversions for metric prefixes, counting units and atomic weights."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
