Detailed Description

Floating point numbers.

Floating point numbers are used to store non integer numeric values. OTX adheres to the W3C definition of the xsd:double data type, which corresponds to the IEEE double-precision 64-bit floating point type in [IEEE 754:2008]. The basic value space of xsd:double consists of the values m × 2^e, where m is an integer whose absolute value is less than 2^53, and e is an integer between -1075 and 970, inclusive.

Note

If a Float declaration is not explicitly initialized, 0.0 is assigned to the declaration.

Conversion Terms

Conversion	Result	Sample
ToBoolean	Returns false if 0.0, otherwise true	Boolean b = ToBoolean(123.456); // Returns true
ToInteger	Returns the integer part (the digits to the left of the decimal point – truncation)	Integer i = ToInteger(123.456); // Returns 123
ToFloat	Returns the copy of the value	Float f = ToFloat(123.456); // Returns 123.456
ToString	Returns the value in decimal string representation	String s = ToString(123.456); // Returns "123.456"
ToByteField	Returns the 64-bit double precision encoded value according to [IEEE 754:2008]	ByteField bf = ToByteField(123.456); // Returns 405EDD2F1A9FBE77

Syntax Declaration

Float Declaration [= FloatLiteral];

Literal

0.0
1.2e34

There are the following additional special Float constants:

Literal	Meaning
-0	Value, which is minus zero
Infinity	Value, which is positive infinity
-Infinity	Value, which is negative infinity
NaN	Value, which is not a number

Sample

Float FloatVariable = 1.2345e67;
