Python frexp() Function Example
1 2 3 4 5 6 7 | # import math library import math print(math.frexp(25)) print(math.frexp(20.3)) print(math.frexp(-20)) print(math.frexp(-13.6)) |
The output of Python frexp() Function:
(0.78125, 5)
(0.634375, 5)
(-0.625, 5)
(-0.85, 4)
Note that in output all the numbers whether they are negative or positive are converted into a pair value (m, e), where m, mantissa, is floating point number and e, exponent, is an integer.
