title Pack Base 60
signature moment.tz.packBase60(Number); // Base60String

Convert a base 10 number to a base 60 string.

moment.tz.packBase60(9);    // 9
moment.tz.packBase60(10);   // a
moment.tz.packBase60(59);   // X
moment.tz.packBase60(1337); // mh

Much like Number.prototype.toFixed, moment.tz.packBase60 accepts a second argument for the number of digits of precision.

moment.tz.packBase60(1.1667,   1); // 1.a
moment.tz.packBase60(20.12345, 3); // k.7op
moment.tz.packBase60(59,       1); // X

A solitary 0 before the decimal point is dropped.

moment.tz.packBase60(1.1667, 1); // 1.a
moment.tz.packBase60(0.1667, 1); // .a

Trailing zeroes after the decimal point are dropped.

moment.tz.packBase60(1/6, 1); // .a
moment.tz.packBase60(1/6, 5); // .a
moment.tz.packBase60(59, 5);  // X
