Better replace all expr with arithmetics by the builtin=faster $(( ))
As the clock is very quickly cycling inside the microsecond part there is always a possibility of these values '00000' to '09999' occurring. These are obviously NOT octal but decimal with leading zeros so......
......I used 'expr' to remove leading zeros otherwise there is a major shell error, thus I can't see how your modification works.
The maths method does not remove those leading zeros...

I want to be able to generate a random number within a korn shell script..
Preferably i would like to be able to state how many digits should be in this random number... ie 4 digits or 5 digits etc
Any ideas? (2 Replies)
I saw this formula to generate random number between two specified values in shell script.the following.
$(((RANDOM%(max-min+divisibleBy))/divisibleBy*divisibleBy+min))

Hi All,
I have extracted some report from database for few activities done.
Now I have a requirement to add some random time(In range of 10-35) in front of each activity.

Hi Guys and gals...
As you know I am getting to grips with POSIX and hit this stumbling block.
Generating two random numbers 0 to 255 POSIXly. Speed in not important hence the 'sleep 1' command.
I have done a demo that works, but it sure is ugly! Is there a better way?

Hi all...
This is just a fun project to see if it is possible to get a square root of a positive integer from 1 to 9200000 to 6 decimal places on a 64 bit architecture machine.
It is coded around dash and the results show the values from 0 to 10000.
Complex numbers can easily be catered for by... (3 Replies)

strtol
strtol(3C)strtol(3C)NAME
strtol(), atol(), atoll(), atoi(), strtoul(), strtoll(), strtoull() - convert string to integer
SYNOPSIS DESCRIPTION
or converts the character string pointed to by str to or representation, respectively. or converts the character string pointed to by str
to or representation, respectively. The string is scanned up to the first character inconsistent with the base. Leading "white-space"
characters (as defined by in ctype(3C)) are ignored. If no conversion can take place, zero is returned.
If base is greater than or equal to 2 and less than or equal to 36, it is used as the base for conversion. After an optional leading sign,
leading zeros are ignored, and or is ignored if base is 16.
If base is zero, the string itself determines the base as follows: after an optional leading sign, a leading zero indicates octal conver-
sion; a leading or indicates hexadecimal conversion. Otherwise, decimal conversion is used.
If the value of ptr is not a pointer to the character terminating the scan is returned in the location pointed to by ptr. If no integer
can be formed, the location pointed to by ptr is set to str, and zero is returned.
