Vectors and MatricesĪ matrix is a two-dimensional rectangular array of mathematical objects. If interval calculation using variance formula is activated (default), the interval represents the standard uncertainty (deviation) of the value. If the read precision option is activated, decimal numbers are interpreted as an interval between the numbers that are normally rounded to the entered number (e.g. IntervalsĪ number interval can be entered using the interval() function, the uncertainty() function, or using "±" or "+/-" (e.g. A number immediately preceded "0b", "0o", "0d" or "0x" are interpreted as a number with base 2, 8, 12 or 16, respectively (e.g. Sexagesimal numbers (and time) can be entered directly using colons (e.g. "E" (or "e") can be considered as a shortcut for writing many zeroes and is equivalent to multiplication by 10 raised to the power of the right-hand value (e.g. Spaces between digits are ignored ("5 5 = 55"). The imaginary part of complex numbers are written with as regular number followed by the special variable "i" (can be changed to a "j"), which represents the square root of -1. Numbers include integers, real numbers, and complex numbers. If comma is used as decimal sign, the dot is still kept as an alternative decimal sign, if not explicitly deactivated. These are the regular numbers composed by digits 0-9 and a decimal sign - a dot, or a comma if it is the default decimal point in the locale/language used.
