Detailed Description
YCPValueRep representing a floating point number. The precision of the floating point number a YCPFloatRep is representing is not specified, because it would be very difficult to guarantee a certain precision platform independently and because this is not neccessary.
YCP Syntax: Like in C. The decimal point is obligatory.
1.0, -0.6, 0.9e-16, ...
Constructor & Destructor Documentation
|
protected |
Creates a new YCPFloatRep object with the value given in v.
|
protected |
Creates a new YCPFloatRep object from its ASCII representation
- Parameters
-
r string like '18.8e-17'
References v.
Member Function Documentation
Compares two YCPFloats for equality, greaterness or smallerness.
- Parameters
-
v value to compare against
- Returns
- YO_LESS, if this is smaller than v, YO_EQUAL, if this is equal to v, YO_GREATER, if this is greater to v
References v, YO_EQUAL, YO_GREATER, and YO_LESS.

Output value as bytecode to stream
Implements YCPElementRep.
References toString(), and Bytecode::writeString().
|
virtual |
Returns an ASCII representation of this value. Note that this must alway contain either a decimal point, or an exponent symbol in order to keep up the axiom, that the syntactical representation of a YCP value uniquely describes its type. Examples: 0.0, 1e10, -17.0e8
Implements YCPElementRep.
References v.
Referenced by toStream(), and toXml().

virtual |
Implements YCPValueRep.
References toString().
| double YCPFloatRep::value | ( | ) | const |
Returns the value of this object in form of a C value of type double.
