strFormatNumber

strFormatNumber(
  const val,      // value to format
  const width,    // width of field
  [const frac])   // # of fractional digits (default = 0)

Formats a number for output. The result is a string of width characters with the value right adjusted. If the value does not fit into width, the result will be as long as the value requires at least.

Examples:

strFormatNumber(1.5, 10, 2);      // '      1.50'
strFormatNumber(123.456, 10, 2);  // '    123.45'
strFormatNumber(123.456, 10);     // '       123'
