### MathExtensions1.0 Errata

The Math.toScientific rounding bug has been resolved, utilizing greenfly's solution

// ############## greenfly's rounding solution ###############
// I left his comments in, but changed the condition to round down
// negative numbers as well, adding a second call to formatDecimals.
// disregard expo_fact - it isn't used here
// ###############################################
// by not dividing by "expo_fact" at the end, we should have the number
// in the desired format: X.XXX, e.g. 3.234
// however, it is possible that by rounding in the step above, we've increased
// the number to XX.XXX, e.g. 9.999999 went to 10.00
// so we need to check for this condition
if (mantissa>=10 || mantissa<=-10) {
mantissa /= 10;
mantissa = Math.formatDecimals(mantissa,sigDigs-1);
exponent++;
}

Updated extensions:

MathExtensions1.1.as

Here is Robert's revised function:
``` Math.toScientific = function(num,sigDigs) {     num = Number(num);     if (isNaN(num)) return num;     var exponent = Math.floor(Math.log(Math.abs(num))/Math.LN10);     if (num==0) exponent = 0;     var tenToPower = Math.pow(10,exponent);     var mantissa = num/tenToPower;     mantissa = Math.formatDecimals(mantissa,sigDigs-1);     if (mantissa>=10 || mantissa<=-10) {         mantissa /= 10;         mantissa = Math.formatDecimals(mantissa,sigDigs-1);         exponent++;     }     var output = mantissa;     if (exponent!=0) {         output += "e"+exponent;         return(output);     } }; //Robert Penner May 2001 - www.robertpenner.com ```
