toFixed vs toPrecision vs Math.round() vs bitwise, also trunc, floor
Compares built in and bitwise operators. Specifically, toFixed(), toPrecision(), and Math.round(), and then bit shifting >> 0. In some cases, to places, so *100 and /100. Also tested floor() and trunc() versus the bit mask of |0 (bitwise or). The bitwise tests that are "signed" have the needed ternary statement, whereas the "UNsigned" versions do not. |
