Hello @coding123c ,
NumPy supports a much greater variety of numerical types than Python does.
int32-: The range of integers lies between Integer (-2147483648 to 2147483647)
int64-: The range of integers lies between (-9223372036854775808 to 9223372036854775807)
float64-: Double precision float: sign bit, 11 bits exponent, 52 bits mantissa.
The 64 refers to the memory allocated to store data in each cell which effectively relates to how many digits it can store in each “cell”.
