i seem to have found a bug in $calc which i have only just noticed when it reaches a certain amount of numbers it just displays zeros instead of the actuall number heres how i found it i found it by calculating bytes upto a yotta byte for example 1 byte tymes 1024 = 1kb 1kb times 1024 = 1mb heres the exact figures to show you the pattern that emmerges

1024
1048576
1073741824
1099511627776
1125899906842624
1152921504606846976
1180591620717411303000
1208925819614629174000000

then i times the yottabyte by 1024 as a test so proove my hypothosis

1237940039285380352000000000

as you can see all teh figures after the 19th are 0 and

the actual answers for the last 3 numbers should be

1180591620717411303424
1208925819614629174706176
