| 110 | NAME: inverse_binary |
---|
| 111 | |
---|
| 112 | PURPOSE: inverse function of the binary.pro function => given a |
---|
| 113 | input array of 0/1, return its corresponding byte/integer/long |
---|
| 114 | representation |
---|
| 115 | |
---|
| 116 | CATEGORY: |
---|
| 117 | |
---|
| 118 | CALLING SEQUENCE: res = inverse_binary(binnum) |
---|
| 119 | |
---|
| 120 | INPUTS: |
---|
| 121 | binnum must be a binary type array containing only 0 and 1. |
---|
| 122 | According to binary.pro outputs, binnum array must have the |
---|
| 123 | following dimensions values: (8, t, d1, d2...) |
---|
| 124 | t gives the output type: t = 1 -> byte |
---|
| 125 | t = 2 -> integer |
---|
| 126 | t = 4 -> long |
---|
| 127 | |
---|
| 128 | (d1, d2...) are the output dimensions |
---|
| 129 | |
---|
| 130 | KEYWORD PARAMETERS: no |
---|
| 131 | |
---|
| 132 | OUTPUTS: a byte/integer/long array with (d1, d2...) dimensions |
---|
| 133 | |
---|
| 134 | COMMON BLOCKS: no |
---|
| 135 | |
---|
| 136 | RESTRICTIONS:the binary number can represent only byte/integer/long |
---|
| 137 | |
