This function is based on the math routines available through your browser. Hence it is limited to dealing with values in the +- (2**32)-1 (typically) on most of the "newer" browsers.

Furthermore, int2dollars() has to additional arguments for prefixing and suffixing negative values (such as a <font...> tag to turn the value red). Within this script there is a function "doit()" that exemplifies the calling conventions. For the purposes of example, if you enter a negative value into the "number" field, the "doit()" invocation of int2dollars() will prepend and append an "x" to the value that will be written into the "dollars" field.
