toint64
Converts values of any snumeric data type or string to values of type int64 (64 bit long, or long long).
Available in version 5.2.0 and later.
Prototype
function toint64 ( input_val : snumeric data type or string ) return_val [dimsizes(input_val)] : int64
Arguments
input_valA variable of any snumeric data type or string of any dimension.
Return value
Returns int64s. 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 an int64 will be returned as a missing value.
Description
This function converts any snumeric data or string to int64 values. If the input is float or double, then the fractional part is truncated.
Any input value that is out of range for an int64 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 an int64. 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.
