* added support for word size suffix in getToken * start modifying number(string) to support word size suffix for signed integers * word size suffixes for Number * initial support for BigNumber * fix linter issues * remove unused variable * start extending bitwise operators for Number for values greater than 32 bits * Revert "start extending bitwise operators for Number for values greater than 32 bits" This reverts commit 6fac1a7b10665a221ab5de521c08fa9fcf959eb1. * add a test for 53 bit literal * added an optional second argument to bin, oct, and hex to allow formatting signed numbers with custom word size * removed size checks * Attempted to extend bin, oct, hex format functions to work with BigNumber, but not working fully. Apparently Decimal.js toString method doesn't take a base parameter like js number does. I guess I have to do the formatting myself. * Added n2base function to do formatting for BigNumber. * Added check for zero in n2base. * Removed old failing tests. * Added some tests (failing). * Extended 'format' function with 'base' and 'wordSize' options and changed 'bin', 'oct', and 'hex' to use 'format' function. * Fixed lint issues. * Fixed issues related to the merge. * Corrected a test. * Fixed bignumber formatter. * Added tests for math.format with 'base' and 'wordSize' options. * Fixed lint issue. * Changed 'base' option to 'bin', 'oct', and 'hex' values for 'notation' option of 'format' function. * Added word size suffix to the output of format, bin, oct, and hex. * Updated documentation.
