flt2dble

Converts values of type float to values of type double and preserves metadata.

Prototype

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl" ; This library is automatically loaded
 ; from NCL V6.2.0 onward.
 ; No need for user to explicitly load.
	function flt2dble (
		x : float 
	)
	return_val [dimsizes(x)] : double

Arguments

An array of any dimensionality and of type float.

Return value

An array of the same size as x and of type double.

Description

This function converts values of type float to values of type double and preserves metadata.

Note: this function is slightly different than the built-in set of conversion functions (like floattointeger and shorttobyte), because it requires loading the "contributed.ncl" script and it preserves metadata. It has a slightly different naming style than the built-in functions, just to set it apart from these other functions.

Examples

Example 1

 diri = "./"
 fili = "V22_GPCP.1979-2010.nc"
 f = addfile(diri+fili, "r")
 prc = flt2dble(f->PREC)
 pmsg = prc@_FillValue ; convenience
 printVarSummary(prc)
 printMinMax(prc,0)
