Datatypes supported by Numpy

Data type Description bool_ Boolean (True or False) stored as a byte int_ Default integer type (same as C long; normally either int64 or int32) intc Identical to C int (normally int32 or int64) intp Integer used for indexing (same as C size_t; normally either int32 or int64) int8 Byte (–128 to 127) int16 Integer (–32768 to 32767) int32 Integer (–2147483648 to 2147483647) int64 Integer (–9223372036854775808 to 9223372036854775807) uint8 Unsigned integer (0 to 255) uint16 Unsigned integer (0 to 65535) uint32 Unsigned integer (0 to 4294967295) uint64 Unsigned integer (0 to 18446744073709551615) float_ Shorthand for float64 float16 Half precision float: sign bit, 5-bit exponent, 10-bit mantissa float32 Single precision float: sign bit, 8-bit exponent, 23-bit mantissa float64 Double precision float: sign bit, 11-bit exponent, 52-bit mantissa complex_ Shorthand for complex128 complex64 Complex number, represented by two 32-bit floats (real and imaginary components) complex128 Complex number
