Get the Machine limits information for float with instances in Python
To get the machine limits information for float types, use the numpy.finfo() method in Python Numpy. The first parameter is the float i.e. the kind of float data type to get information about.
Steps
At first, import the required library −
import numpy as np
The min is the minimum value of given dtype and max is the minimum value of given dtype.
Checking for float16 type with instances −
a = np.finfo(np.float16(12.5))
print("Minimum of float16 type...\n",a.min)
print("Maximum of float16 type...\n",a.max)Checking for float32 type with instances −
b = np.finfo(np.float32(30.5))
print("\nMinimum of float32 type...\n",b.min)
print("Maximum of float32 type...\n",b.max)Checking for float type with instances −
c = np.finfo(np.float64(55.9))
print("\nMinimum of float64 type...\n",c.min)
print("Maximum of float64 type...\n",c.max)Example
import numpy as np
# To get the machine limits information for float types, use the numpy.finfo() method in Python Numpy
# The first parameter is the float i.e. the kind of float data type to get information about.
# Checking for float16 type with instances
# The min is the minimum value of given dtype.
# The max is the minimum value of given dtype.
a = np.finfo(np.float16(12.5))
print("Minimum of float16 type...\n",a.min)
print("Maximum of float16 type...\n",a.max)
# Checking for float32 type with instances
b = np.finfo(np.float32(30.5))
print("\nMinimum of float32 type...\n",b.min)
print("Maximum of float32 type...\n",b.max)
# Checking for float type with instances
c = np.finfo(np.float64(55.9))
print("\nMinimum of float64 type...\n",c.min)
print("Maximum of float64 type...\n",c.max)Output
Minimum of float16 type... -65500.0 Maximum of float16 type... 65500.0 Minimum of float32 type... -3.4028235e+38 Maximum of float32 type... 3.4028235e+38 Minimum of float64 type... -1.7976931348623157e+308 Maximum of float64 type... 1.7976931348623157e+308
