# Glib::Param::Double(3pm)

Wrapper for double parameters in GLib

## NAME

Glib::Param::Double -  Wrapper for double parameters in GLib

## HIERARCHY

```

## DESCRIPTION

This page documents the extra accessors available for both of the floating-point type paramspecs: Float and Double.  Perl really only supports doubles, so all of these methods return NVs (that is, the C type "double"); the distinction of size is important to the underlying C library and also determines the data value range.
