Member Function Documentation

compare()

virtual int utl::Float::compare ( const Object &  rhs ) const

virtual

Compare with another object.

If no overridden version succeeds in doing the comparison, then an attempt will be made to re-start the comparison process using one or both of the objects' keys. Usually, an override of compare() should call the superclass's compare() if it doesn't know how to compare itself with the rhs object.

See also

getKey

Returns

< 0 if self < rhs, 0 if self = rhs, > 0 if self > rhs

Parameters

rhs	object to compare with

Reimplemented from utl::Number< double >.

serialize()

virtual void utl::Float::serialize ( Stream &  stream, uint_t  io, uint_t  mode = ser_default  )

virtual

Serialize to or from a stream.

This is the only virtual method for serialization. You must override this in any class that has data to be serialized, and ensure that the superclass's serialize() gets called.

Parameters

stream	stream to serialize from/to
io	see utl::io_t
mode	see utl::serialize_t

Reimplemented from utl::Number< double >.

toString() [1/2]

virtual String utl::Float::toString ( ) const

virtual

Return a string representation of self.

Reimplemented from utl::Object.

Reimplemented in utl::Duration.

toString() [2/2]

String utl::Float::toString

(

uint_t

digits

)

const

Get a string representation.

Returns

string representation

Parameters

digits

number of digits of precision (uint_t_max for maximum)

set()

virtual Number<double>& utl::Float::set ( const String &  )

virtual

Set from a string representation.

Reimplemented from utl::Number< double >.

Reimplemented in utl::Duration.

isInt()

bool utl::Float::isInt ( ) const

inline

Determine whether the number is an integer (has no fractional component).

Definition at line 73 of file Float.h.

abs()

Float utl::Float::abs ( ) const

inline

Get the absolute value of self.

Definition at line 80 of file Float.h.

mod()

Float utl::Float::mod

(

const Float &

rhs

)

const

Get the result of self modulo rhs.
