Numeric functions are discussed in set 1 below
Mathematical Functions in Python | Set 1 ( Numeric Functions)
Logarithmic and power functions are discussed in this set.
1. exp(a) :- This function returns the value of e raised to the power a (e**a) .
2. log(a, b) :- This function returns the logarithmic value of a with base b. If base is not mentioned, the computed value is of natural log.
# Python code to demonstrate the working of # exp() and log() # importing "math" for mathematical operations import math # returning the exp of 4 print ("The e**4 value is : ", end="") print (math.exp(4)) # returning the log of 2,3 print ("The value of log 2 with base 3 is : ", end="") print (math.log(2,3)) |
Output:
The e**4 value is : 54.598150033144236 The value of log 2 with base 3 is : 0.6309297535714574
3. log2(a) :- This function computes value of log a with base 2. This value is more accurate than the value of the function discussed above.
4. log10(a) :- This function computes value of log a with base 10. This value is more accurate than the value of the function discussed above.
# Python code to demonstrate the working of # log2() and log10() # importing "math" for mathematical operations import math # returning the log2 of 16 print ("The value of log2 of 16 is : ", end="") print (math.log2(16)) # returning the log10 of 10000 print ("The value of log10 of 10000 is : ", end="") print (math.log10(10000)) |
Output:
The value of log2 of 16 is : 4.0 The value of log10 of 10000 is : 4.0
5. pow(a, b) :- This function is used to compute value of a raised to the power b (a**b).
6. sqrt() :- This function returns the square root of the number.
# Python code to demonstrate the working of # pow() and sqrt() # importing "math" for mathematical operations import math # returning the value of 3**2 print ("The value of 3 to the power 2 is : ", end="") print (math.pow(3,2)) # returning the square root of 25 print ("The value of square root of 25 : ", end="") print (math.sqrt(25)) |
Output:
The value of 3 to the power 2 is : 9.0 The value of square root of 25 : 5.0
