Returns the character represented by the decimal value expr.
Converts a time as returned by the time function to a 9-element array (0:$sec, 1:$min, 2:$hour, 3:$mday, 4:$mon, 5:$year, 6:$wday, 7:$yday, 8:$isdst) with the time analyzed for the Greenwich time zone. $mon has the range 0..11 and $wday has the range 0..6.
Returns the decimal value of expr interpreted as a hex string.
Converts a time as returned by the time function to ctime(3) string. In array context, returns a 9-element array with the time analyzed for the local time zone.
Returns the decimal value of expr interpreted as an octal string. If expr starts off with 0x, interprets it as a hex string instead.
Returns the ASCII value of the first character of expr.
Treats string expr as a vector of unsigned integers, and yields the bit at offset. bits must be between 1 and 32. May have a value assigned to it.
