This is a node.js module to provide useful miscellaneous functions. For example, min(), max(), and cmp() . Almost all these function are trivially short.

Calls process.exit(d) on nextTick. Useful when you print something out then immediately call process.exit(), because sometimes the program exits before the message was printed to stdout.

Returns a string which is str repeated n times. Basically, it is the x operator from Perl.

Returns a random number [n,n+d). If it is called rand(d), then n=0.

There is a problem with some Math functions. For example,

Math.log(1000)/Math.LN10 //=> 2.9999999999999996 oops!

Hence, Math.floor(Math.log(1000)/Math.LN10) returns 2 which is wrong. pseudo_floor(d) returns d if d is within Math.pow(2,-43) of d. 2^-43 was chosen cuz it works on my log10() function for the whole span of the double float number range.

Return log base 10 of d.

Return the base 10 order of magnitude of d.

Returns the smaller value of a or b.

Returns the larger value of a or b.

Returns 1 if a > b, - if a < b, and 0 if a === b.

Returns a new Buffer which is the concatenation of bufs, where bufs is an array of Buffer objects.

Returns true if d is an integer number, and false otherwise.

Returns true if s is a string, and false otherwise.

Returns true if d is a Number, and false otherwise.

Returns true if d is a Function, and false otherwise.
