.SH DESCRIPTION
The QDoubleValidator class provides range checking of floating-point numbers.
.PP
QDoubleValidator provides an upper bound, a lower bound, and a limit on the number of digits after the decimal point. It does not provide a fixup() function.
.PP
See also: QIntValidator.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QDoubleValidator::QDoubleValidator ( QWidget * parent, const char * name = 0 )"
Creates a validator object which accepts all double from 2.7182818 to 3.1415926 (please, no bug reports) with at most seven digits after the decimal point.
.PP
This constructor is not meant to be useful; it is provided for completeness.
.SH "QDoubleValidator::QDoubleValidator ( double bottom, double top, int decimals, QWidget * parent, const char * name = 0 )"
Creates a validator object which accepts all doubles from \fIbottom\fR up to and including \fItop\fR with at most \fIdecimals\fR digits after the decimal point.
.SH "QDoubleValidator::~QDoubleValidator ()"
Deletes the validator and frees any storage and other resources used.
.SH "double QDoubleValidator::bottom () const"
Returns the lowest valid number according to this validator.
.PP
See also: top(), decimals() and setRange().
.SH "int QDoubleValidator::decimals () const"
Returns the largest number of digits a valid number can have after its decimal point.
.PP
See also: bottom(), top() and setRange().
.SH "void QDoubleValidator::setRange ( double bottom, double top, int decimals = 0 ) \fC[virtual]\fR"
Sets the validator to accept numbers from \fIbottom\fR up to and including \fItop\fR with at most \fIdecimals\fR digits after the decimal point.
.SH "double QDoubleValidator::top () const"
Returns the highest valid number according to this validator.
.PP
See also: bottom(), decimals and setRange().
.SH "QValidator::State QDoubleValidator::validate( QString & input, int & ) const"
Returns \fIAcceptable\fR if \fIinput\fR contains a number in the legal
range and format, \fIValid\fR if it contains another number, a number
with too many digits after the decimal point or is empty, and \fIInvalid\fR if \fIinput\fR is not a number.
