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 | Create a data type object. |
| format_parser(formats, names, titles[, ...]) | Class to convert formats, names, titles description to a dtype. |
Data type information¶
| finfo | Machine limits for floating point types. |
| iinfo(type) | Machine limits for integer types. |
| MachAr([float_conv, int_conv, ...]) | 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. |
