Introducció als nombres complexos de Python: Nombres complexos en Python | Set 1 (Introducció) En aquest article es comenten algunes funcions i constants més importants. Operacions sobre nombres complexos : 1. exp() :- Aquesta funció retorna el exponent del nombre complex esmentat en el seu argument. 2. registre (xb) :- Aquesta funció retorna el valor logarítmic de x amb la base 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() :- Aquesta funció retorna el base logística 10 d'un nombre complex. 4. quadrat() :- Això calcula el arrel quadrada 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. isfinit() :- Devolucions cert si tant la part real com la imaginària de nombre complex són finit sinó retorna fals. 6. Per a tu() :- Devolucions cert si és una part real o imaginària de nombre complex és/són infinit sinó retorna fals. 7. isnan() :- Retorna cert si part real o imaginària de nombre complex és 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
Constants Hi ha dues constants definides al mòdul cmath 'pi' que retorna el valor numèric de pi. El segon és 'i' 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
