The number
data type represents a real number. The number
data type can also represent the values positive infinity
, negative infinity
, and NaN
.
The XION Scripting Language Standard states that the number
type must have IEEE single precision or better. The number
type in OpenXION has arbitrary precision: basic arithmetic operations use the number of fractional digits specified by the precision
property, and mathematical functions can use either IEEE double precision or the number of fractional digits specified by the precision
property, depending on the setting of the mathProcessor
property.
A number
can always convert to a string
or a complex
. A number
can convert to an integer
only if its numeric value is a mathematical integer and it is within the range of the integer
type.
An integer
can always convert to a number
. A string
can convert to a number
if it has the correct format, and a complex
can convert to a number
if its imaginary part is zero.
The format used for the conversion of a number
to a string
is determined by the numberFormat
property.
