Examples

Format as Decimal, Hexadecimal, Octal, and Binary

$ qcal format 0xdeadbeef
> dec: 3735928559       hex: 0xdeadbeef         oct: o33653337357           bin: b11011110101011011011111011101111

$ qcal format 0x1234 234 b011101 o24
> dec: 4660         hex: 0x1234         oct: o11064         bin: b1001000110100
> dec: 234          hex: 0xea           oct: o352           bin: b11101010
> dec: 29           hex: 0x1d           oct: o35            bin: b11101
> dec: 20           hex: 0x14           oct: o24            bin: b10100

Swap Endianness of Hexadecimal

$ qcal endian 0x55bd840a78798ad0da853f68974f3d183e2bd1db6a842c1feecf222a00000000
> 0x000000002a22cfee1f2c846adbd12b3e183d4f97683f85dad08a79780a84bd55

$ qcal endian 0xdeadbeef abcdef56
> 0xefbeadde
> 0x56efcdab

Count Byte Length of Hexadecimal

$ qcal bytelen 0xdeadbeef
> 0xdeadbeef:   4 bytes

$ qcal bytelen 0xdeadbeef 0x12
> 0xdeadbeef:   4 bytes
> 0x12:         1 byte

You can use bytelen or len to access this operation.

Count Character Length

$ qcal charlen 0x1234 234 b011101 o24 4
> 0x1234:   4 chars
> 234:      3 chars
> b011101:  6 chars
> o24:      2 chars

Add

$ qcal add 0xFF 30 o24 b111
> dec: 312        hex: 138        oct: 470        bin: 100111000

$ qcal add 30 2 5
> dec: 37         hex: 25         oct: 45         bin: 100101

$ qcal add 21 14
> dec: 35         hex: 23         oct: 43         bin: 100011

Subtract

$ qcal sub 0xFF 30 o24 b111
> dec: 198        hex: c6         oct: 306        bin: 11000110

$ qcal sub 30 2 5
> dec: 23         hex: 17         oct: 27         bin: 10111

$ qcal sub 21 14
> dec: 7          hex: 7          oct: 7          bin: 111

Multiply

$ qcal mul 0xFF 30 o24 b111
> dec: 1071000    hex: 105798     oct: 4053630    bin: 100000101011110011000

$ qcal mul 30 2 5
> dec: 300       hex: 12c         oct: 454        bin: 100101100

$ qcal mul 21 14
> dec: 294        hex: 126        oct: 446         bin: 100100110

Divide

$ qcal div 0xFF 30 o24 b111
> dec: 0          hex: 0          oct: 0          bin: 0

$ qcal div 30 2 5
> dec: 3          hex: 3          oct: 3          bin: 11
