Convert an object to double precision
result = double (x)
The double function typecasts an object x to double
precision. For example, if x is an array of integers, an
array of double types will be returned. If an object cannot be
converted to Double_Type, a type-mismatch error will result.
The double function is equivalent to the typecast operation
typecast (x, Double_Type)
To convert a string to a double precision number, use atoi
function.
