toushort

Converts values of any snumeric data type or string to values of type unsigned short.

Available in version 5.2.0 and later.

Prototype

	function toushort (
		input_val  : snumeric data type or string   
	)

	return_val [dimsizes(input_val)] :  unsigned short

Arguments

input_val

A variable of any snumeric data type or string of any dimension.

Return value

Returns unsigned shorts. If the input variable is float or double, then any fractional part of the input values is truncated. The dimensionality of the output matches that of the input.

Any input value that is out of range for a unsigned short will be returned as a missing value.

Description

This function converts any snumeric data or string to unsigned short values. If the input is float or double, then the fractional part is truncated.

Any input value that is out of range for a unsigned short will be returned as a missing value.

Attributes, with the exception of _FillValue, are not propagated by the conversion functions.

Special considerations apply to how missing values and out-of-range values are handled in the conversion functions. For this function an out-of-range value could be valid in its original type, but not in the valid range of a unsigned short. An out-of-range value is converted to a missing value, but what that missing value is depends on the circumstances of the particular conversion being performed. For example, determination has to be made whether a missing value for a variable to be converted is in the range of the type of the target variable.
