 * moveDecimalAsString
 * This is used by moveDecimal, and does not run parseFloat on the return value.
 * 
 * Normally a decimal place is moved by multiplying by powers of 10
 * Multiplication and division in JavaScript can result in floating point limitations.
 * So use this method to move a decimal place left or right.
 *
 * Parameters:
 * val - The value to be shifted. Can be a number or a string,
 *  but don't include special characters. It should evaluate to a number.
 * left - If true, then move decimal left. If false, move right.
 * places - (optional) If not included, then use the objects this.places
 *  The purpose is so this method can be used independent of the state of the object.
 *
 * The regular expressions:
 * re1
 * Pad with zeros in case there aren't enough numbers to cover the spaces shift.
 * A left shift pads to the left, and a right shift pads to the right.
 * Can't just concatenate. There might be a negative sign or the value could be an exponential.
 *
 * re2
 * Switch the decimal.
 * Need the first [0-9]+ to force the search to start rightmost.
 * The \.? and [0-9]{} criteria are the pieces that will be switched
 *
 * Other notes:
 * This method works on exponential numbers, e.g. 1.7e-12
 * because the regular expressions only modify the number and decimal parts.
 *
 * Mozilla can't handle [0-9]{0} in the regular expression.
 *  Fix: Since nothing changes when the decimal is shifted zero places, return the original value.
 *
 * IE is incorrect if exponential ends in .
 *  e.g. -8500000000000000000000. should be -8.5e+21
 *  IE counts it as -8.5e+22
 *	Fix: Replace trailing period, if there is one, using replace(/\.$/, '').
 *
 * Netscape 4.74 cannot handle a leading - in the string being searched for the re2 expressions.
 *  e.g. /([0-9]*)(\.?)([0-9]{2})/ should match everything in -100.00 except the -
 *  but it matches nothing using Netscape 4.74.
 *  It might be a combination of the * ? special characters.
 *  Fix: (-?) was added to each of the re2 expressions to look for - one or zero times.
