If the input data is binary, the |
| 72 |
+ |
.I \-id |
| 73 |
+ |
or |
| 74 |
+ |
.I \-if |
| 75 |
+ |
option may be given for 64-bit double or 32-bit float values, respectively. |
| 76 |
+ |
Either option may be followed immediately by an optional |
| 77 |
+ |
count, which defaults to 1, indicating the number of double or float |
| 78 |
+ |
binary values to read per record on the input file. |
| 79 |
+ |
(There can be no space between the option and this count.)\0 |
| 80 |

Similarly, the |
| 81 |
+ |
.I \-od |
| 82 |
+ |
and |
| 83 |
+ |
.I \-of |
| 84 |
+ |
options specify binary double or float output, respectively. |
| 85 |
+ |
These options do not need a count, as this will be determined by the |
| 86 |
+ |
number of input channels. |

.PP |

A count can be given as the number of lines to read before |
| 89 |
|
computing a result. |

the input. |

For each blank input line, total produces a result as if the |

end-of-file had been reached. |

If two blank lines immediately follow each other, total closes |

the file and proceeds to the next one (after reporting the result). |

In addition, the |
| 106 |
|
.I \-r |

option can be specified to override reinitialization and thus |

give a running total every N lines. |

give a running total every N lines (or every blank line). |

If the end of file is reached, the current total is printed |

.SH EXAMPLE |
| 121 |
|
To compute the RMS value of colon-separated columns in a file: |
| 122 |
|
.IP "" .2i |
| 123 |
< |
total -t: -m -s2 input |
| 123 |
> |
total \-t: \-m \-s2 input |

To produce a running product of values from a file: |
| 126 |
|
.IP "" .2i |
| 127 |
< |
total -p -1 -r input |
| 127 |
> |
total \-p \-1 \-r input |

|
.SH BUGS |
| 129 |
|
If the input files have varying numbers of columns, mean values |
| 130 |
|
will certainly be off. |
