Convert Decimal to Binary & Hex, and vice versa

[Kong Kian Chay]

Anybody knows of any commands / utilities / freewares for HP-UX 10.20 or 11.0 which can -
a)Convert from Decimal to Binary, & vice versa.
b)Convert from Decimal to Hexadecimal, & vice versa.

Hi!

dtcalc can convert them. Or you can write a short C program using scanf and printf.

Hi,

you could use the bc command within a script ie:
-------------------------------
#!/bin/sh
# decimal to binary
dec2bin()
{
{
echo "obase=2"
echo "$1"
echo "quit"
}|bc
}

dec=255 # example
bin=$(dec2bin $dec)
echo $bin
-----------------------------------------
#!/bin/sh
# binary to decimal
bin2dec()
{
{
echo "ibase=2"
echo "$1"
echo "quit"
}|bc
}

bin=010101 # example
dec=$(bin2dec $bin)
echo $dec
-----------------------------------
#!/bin/sh
# decimal to hex
dec2hex()
{
{
echo "obase=16"
echo "$1"
echo "quit"
}|bc
}

dec=255 # example
hex=$(dec2hex $dec)
echo $hex
--------------------------------------
#!/bin/sh
# hex to decimal
hex2dec()
{
{
echo "ibase=16"
echo "$1"
echo "quit"
}|bc
}

hex=0A # example
dec=$(hex2dec $hex)
echo $dec

I cannot resist to reply:

Use the "printf" command... Yes, it exist.

$ printf "dec -> hex %d = %x\n" 32 32

$ printf "hex -> dec %x = %d\n" 0x20 0x20
