Įvadas į python kompleksinius skaičius: Sudėtiniai skaičiai Python | 1 rinkinys (įvadas) Šiame straipsnyje aptariamos kai kurios svarbesnės funkcijos ir konstantos. Operacijos su kompleksiniais skaičiais : 1. exp() :- Ši funkcija grąžina eksponentas jo argumente nurodyto kompleksinio skaičiaus. 2. log(xb) :- Ši funkcija grąžina x logaritminė reikšmė su baze 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(z10)) The exponent of complex number is : (1.4686939399158851+2.2873552871788423j) The log(base 10) of complex number is : (0.15051499783199057+0.3410940884604603j)
3. log10() :- Ši funkcija grąžina rąsto pagrindas 10 kompleksinio skaičiaus. 4. sqrt () :- Tai apskaičiuoja kvadratinė šaknis 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)) The log10 of complex number is : (0.15051499783199057+0.3410940884604603j) The square root of complex number is : (1.09868411346781+0.45508986056222733j)
5. begalinis() :- Grįžta tiesa, jei ir tikroji, ir įsivaizduojama dalis kompleksinio skaičiaus yra baigtinis kitu atveju grąžinama klaidinga. 6. Tau () :- Grįžta tiesa, jei tikra arba įsivaizduojama dalis kompleksinio skaičiaus yra/yra begalinis kitu atveju grąžinama klaidinga. 7. isnan() :- Grąžina tiesa, jei tikroji arba menama dalis kompleksinio skaičiaus yra 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(xy); # converting x and a into complex number w = complex(xa); # converting x and b into complex number v = complex(xb); # 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') Complex number is finite Complex number is infinite Complex number is NaN
Konstantos Cmath modulyje yra apibrėžtos dvi konstantos "pi" kuri grąžina skaitinę pi reikšmę. Antrasis yra 'ir' 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) The value of pi is : 3.141592653589793 The value of exponent is : 2.718281828459045
