Data type routines

can_cast (fromtype, totype) Returns True if cast between data types can occur without losing precision.
common_type (*arrays) Return a scalar type which is common to the input arrays.
obj2sctype (rep[, default])

Creating data types

dtype (obj[, align, copy]) Create a data type object.
format_parser Class to convert formats, names, titles description to a dtype.

Data type information

finfo (dtype) Machine limits for floating point types.
iinfo (type) Machine limits for integer types.
MachAr Diagnosing machine parameters.

Data type testing

issctype (rep) Determines whether the given object represents a scalar data-type.
issubdtype (arg1, arg2) Returns True if first argument is a typecode lower/equal in type hierarchy.
issubsctype (arg1, arg2) Determine if the first argument is a subclass of the second argument.
issubclass_ (arg1, arg2)
find_common_type (array_types, scalar_types) Determine common type following standard coercion rules.

Miscellaneous

typename (char) Return a description for the given data type code.
sctype2char (sctype) Return the string representation of a scalar dtype.
mintypecode (typechars[, typeset, default]) Return the character for the minimum-size type to which given types can be safely cast.
