numpy.mintypecode¶

numpy.mintypecode(typechars,typeset='GDFgdf',default='d')[source]¶

Return the character for the minimum-size type to which given types canbe safely cast.

The returned type character must represent the smallest size dtype suchthat an array of the returned type can handle the data from an array ofall types intypechars (or iftypechars is an array, then itsdtype.char).

Parameters:

typechars:list of str or array_like If a list of strings, each string should represent a dtype.If array_like, the character representation of the array dtype is used. typeset:str or list of str, optional The set of characters that the returned character is chosen from.The default set is ‘GDFgdf’. default:str, optional The default character, this is returned if none of the characters intypechars matches a character intypeset.

Returns:

typechar:str The character representing the minimum-size type that was found.
