Type: | Command |
|
Description: | For a polynomial P and a closed interval [a, b], STURMAB determines the number of zeroes P has | |
| in [a, b] |
|
Access: | Arithmetic, !ÞPOLYNOMIAL !« | |
Input: | A polynomial P |
|
Output: | A list containing a number that is the same sign as P(a) and the number of zeroes P has in [a, b]. | |
Flags: | Exact mode must be set (flag |

| Numeric mode must not be set (flag |
|
| Radians mode must be set (flag |

Description: | Set Wordsize Command: Sets the current binary integer wordsize to n bits, where n is a value | |
| from 1 through 64 (the default is 64). |
|
| Values of n less than 1 or greater than 64 are interpreted as 1 or 64, respectively. | |
| If the wordsize is smaller than an integer entered on the command line, then the most significant | |
| bits are not displayed upon entry. The truncated bits are still present internally (unless they exceed | |
| 64), but they are not used for calculations and they are lost when a command uses this binary | |
| integer as an argument. |
|
| Results that exceed the given wordsize are also truncated to the wordsize. | |

SUBType: Command Operation
Description: Subset Command: Returns the portion of a string or list defined by specified positions, or returns the rectangular portion of a graphics object or PICT defined by two corner pixel coordinates.
If nend position is less than nstart position, SUB returns an empty string or list. Values of n less than 1 are treated as 1; values of n exceeding the length of the string or list are treated as that length.
For graphics objects, a
