3536 DEFUN (format, args, , |

| 3538 @deffn {Command} format options\n\ | |
| 3539 Control the format of the output produced by @code{disp} and Octave's\n\ | |
| 3540 normal echoing mechanism. Valid options are listed in the following\n\ | |
| 3541 table.\n\ | |
| 3542 \n\ | |
| 3543 @table @code\n\ | |
| 3544 @item short\n\ | |
| 3545 Octave will try to print numbers with at\n\ | |
| 4509 | 3546 least 5 significant figures within a field that is a maximum of 10\n\ |
| 3547 characters wide (not counting additional spacing that is added between\n\ | |
| 3548 columns of a matrix).\n\ | |
| 3372 | 3549 \n\ |
| 3550 If Octave is unable to format a matrix so that columns line up on the\n\ | |
| 3551 decimal point and all the numbers fit within the maximum field width,\n\ | |
| 3552 it switches to an @samp{e} format.\n\ | |
| 3553 \n\ | |
| 3554 @item long\n\ | |
| 3555 Octave will try to print numbers with at least 15 significant figures\n\ | |
| 4509 | 3556 within a field that is a maximum of 20 characters wide (not counting\n\ |
| 3557 additional spacing that is added between columns of a matrix).\n\ | |
| 3372 | 3558 \n\ |
| 3559 As will the @samp{short} format, Octave will switch to an @samp{e}\n\ | |
| 3560 format if it is unable to format a matrix so that columns line up on the\n\ | |
| 3561 decimal point and all the numbers fit within the maximum field width.\n\ | |
| 3562 \n\ | |
| 3563 @item long e\n\ | |
| 3564 @itemx short e\n\ | |
| 3565 The same as @samp{format long} or @samp{format short} but always display\n\ | |
| 3566 output with an @samp{e} format. For example, with the @samp{short e}\n\ | |
| 4509 | 3567 format, @code{pi} is displayed as @code{3.14e+00}.\n\ |
| 3372 | 3568 \n\ |
| 3569 @item long E\n\ | |
| 3570 @itemx short E\n\ | |
| 3571 The same as @samp{format long e} or @samp{format short e} but always\n\ | |
| 3572 display output with an uppercase @samp{E} format. For example, with\n\ | |
| 4509 | 3573 the @samp{long E} format, @code{pi} is displayed as\n\ |
| 3372 | 3574 @code{3.14159265358979E+00}.\n\ |
| 4509 | 3575 @item long g\n\ |
| 3576 @itemx short g\n\ | |
| 7001 | 3577 Choose between normal @samp{long} (or @samp{short}) and\n\ |
| 4509 | 3578 @samp{long e} (or @samp{short e}) formats based on the magnitude\n\ |
| 3579 of the number. For example, with the @samp{short g} format,\n\ | |
| 3580 @code{pi .^ [2; 4; 8; 16; 32]} is displayed as\n\ | |

| 3614 Print output in free format, without trying to line up columns of\n\ | |
| 3615 matrices on the decimal point. This also causes complex numbers to be\n\ | |
| 3616 formatted like this @samp{(0.604194, 0.607088)} instead of like this\n\ | |
| 3617 @samp{0.60419 + 0.60709i}.\n\ | |

| 3372 | 3627 Print a @samp{+} symbol for nonzero matrix elements and a space for zero\n\ |
| 3628 matrix elements. This format can be very useful for examining the\n\ | |
| 3629 structure of a large matrix.\n\ | |
| 3630 \n\ | |
| 4632 | 3631 The optional argument @var{chars} specifies a list of 3 characters to use\n\ |
| 3632 for printing values greater than zero, less than zero and equal to zero.\n\ | |
| 3633 For example, with the @samp{+ \"+-.\"} format, @code{[1, 0, -1; -1, 0, 1]}\n\ | |
| 3634 is displayed as\n\ | |

| 3647 memory. For example, on a workstation which stores 8 byte real values\n\ | |
| 3648 in IEEE format with the least significant byte first, the value of\n\ | |
| 3649 @code{pi} when printed in @code{hex} format is @code{400921fb54442d18}.\n\ | |

| 3372 | 3656 Print the bit representation of numbers as stored in memory.\n\ |
