I'm looking for a simple javascript financial RATE function, and I found this one. But it seems too difficult to understand. I want to simplify this function, and I need your help. If anyone has a simplest function, please answer. (It's a excel RATE function equivalent.) var rate = function(nper, pmt, pv, fv, type, guess) { if (guess == null) guess = 0.01; if (fv == null) fv = 0; if (type == null) type = 0; var FINANCIAL_MAX_ITERATIONS = 128;//Bet accuracy with 128 var FINANCIAL_PRECISION = 0.0000001;//1.0e-8 var y, y0, y1, x0, x1 = 0, f = 0, i = 0; var rate = guess; if (Math.abs(rate) <
