Monimutkaiset numerot Pythonissa | Joukko 2 (tärkeät funktiot ja vakiot)
Johdatus python-kompleksilukuihin: Monimutkaiset numerot Pythonissa | Sarja 1 (johdanto) Joitakin tärkeämpiä funktioita ja vakioita käsitellään tässä artikkelissa. Operaatiot kompleksiluvuilla : 1. exp() :- Tämä funktio palauttaa eksponentti argumentissa mainitusta kompleksiluvusta. 2. loki(xb) :- Tämä funktio palauttaa x:n logaritminen arvo, jonka kanta on b both mentioned in its arguments. If base is not specified natural log of x is returned. Python
# Python code to demonstrate the working of # exp() log() # importing 'cmath' for complex number operations import cmath import math # Initializing real numbers x = 1.0 y = 1.0 # converting x and y into complex number z = complex ( x y ); # printing exponent of complex number print ( 'The exponent of complex number is : ' end = '' ) print ( cmath . exp ( z )) # printing log form of complex number print ( 'The log(base 10) of complex number is : ' end = '' ) print ( cmath . log ( z 10 ))
Output: The exponent of complex number is : (1.4686939399158851+2.2873552871788423j) The log(base 10) of complex number is : (0.15051499783199057+0.3410940884604603j)3. log10() :- Tämä funktio palauttaa hirsipohja 10 kompleksiluvusta. 4. sqrt() :- Tämä laskee neliöjuuri of a complex number. Python
# Python code to demonstrate the working of # log10() sqrt() # importing 'cmath' for complex number operations import cmath import math # Initializing real numbers x = 1.0 y = 1.0 # converting x and y into complex number z = complex ( x y ); # printing log10 of complex number print ( 'The log10 of complex number is : ' end = '' ) print ( cmath . log10 ( z )) # printing square root form of complex number print ( 'The square root of complex number is : ' end = '' ) print ( cmath . sqrt ( z ))
Output: The log10 of complex number is : (0.15051499783199057+0.3410940884604603j) The square root of complex number is : (1.09868411346781+0.45508986056222733j)5. isfinite() :- Palauttaa totta, jos sekä todellinen että kuvitteellinen osa kompleksiluvuista ovat rajallinen muuten palauttaa false. 6. Sinulle() :- Palauttaa totta, jos joko todellinen tai kuvitteellinen osa kompleksiluvun on/ovat ääretön muuten palauttaa false. 7. isnan() :- Palauttaa todeksi, jos joko todellinen tai kuvitteellinen osa kompleksiluvusta on NaN else returns false. Python
# Python code to demonstrate the working of # isnan() isinf() isfinite() # importing 'cmath' for complex number operations import cmath import math # Initializing real numbers x = 1.0 y = 1.0 a = math . inf b = math . nan # converting x and y into complex number z = complex ( x y ); # converting x and a into complex number w = complex ( x a ); # converting x and b into complex number v = complex ( x b ); # checking if both numbers are finite if cmath . isfinite ( z ): print ( 'Complex number is finite' ) else : print ( 'Complex number is infinite' ) # checking if either number is/are infinite if cmath . isinf ( w ): print ( 'Complex number is infinite' ) else : print ( 'Complex number is finite' ) # checking if either number is/are infinite if cmath . isnan ( v ): print ( 'Complex number is NaN' ) else : print ( 'Complex number is not NaN' )
Output: Complex number is finite Complex number is infinite Complex number is NaNVakiot Cmath-moduulissa on määritelty kaksi vakiota "pi" joka palauttaa pi:n numeerisen arvon. Toinen on 'ja' which returns the numerical value of exponent. Python
# Python code to demonstrate the working of # pi and e # importing 'cmath' for complex number operations import cmath import math # printing the value of pi print ( 'The value of pi is : ' end = '' ) print ( cmath . pi ) # printing the value of e print ( 'The value of exponent is : ' end = '' ) print ( cmath . e )
Output: The value of pi is : 3.141592653589793 The value of exponent is : 2.718281828459045Monimutkaiset numerot Pythonissa | Joukko 3 (trigonometriset ja hyperboliset funktiot)
