math moduli. Matematik funksiyalar
math moduli sonlar bilan ishlash uchun qo’shimcha funksiyalarni o’z ichiga oladi. Bu modulan foydalanishdan oldin quyidagi instruksiya bo’yicha chaqirib olinadi:
import math
Kompleks sonlar bilan ishlashda cmath kutubxonasidan foydalanish zarur. Math moduli quyidagi standart konstantalarni taqdim qiladi:

• 
  pi – pi sonini qaytaradi:
  

>>> import math
>>> math.pi
3.141592653589793

• 
  е – е konstantasi qiymatini qaytaradi:
  

>>> math.e
2.718281828459045
Sonlar bilan ishlashning asosiy funksiyalarni sanab o’tamiz:

• 
  sin(), cos(), tan() – standart trigonoometrik funksiyalar (sinus, kosinus, tangens). Qiymatlar radianda beriladi;
  
• 
  asin (), acos (), atan () - teskari trigonometric funksiyalar (arksinus, arkkosinus,arktangens). Natija radianda qaytariladi;
  
• 
  degrees () – radiandan gradusga o’tkazish:
  

>>> math.degrees (math.pi)
180 .0

• 
  radians () – gradusdan radianga o’tkazish:
  

>>> math.radians(l80.0)
3.141592653589793

• 
  ехр() - eksponenta;
  
• 
  log ( [, ]) - ko’rsatilga asos bo’yicha logarifm. Agar asos ko’rsatilmasa natural logarifm deb hisoblanadi (е asosga ko’ra);
  
• 
  log10 () – o’nlik logarifm ;
  
• 
  log2 () – 2 asosga ko’ra logarifm;
  
• 
  sqrt () – kvadrat ildiz:
  

>>> math.sqrt(100), math.sqrt(25)
(10.0, 5.0)

• 
  ceil () – eng yaqin katta songa yaxlitlash:
  

>>> math.ceil(5.49), math.ceil(5.50), math.ceil(5.51)
(6, 6, 6)

• 
  floor () - – eng yaqin kichik songa yaxlitlash:
  

>>> math.floor(5.49), math.floor (5.50), math.floor(5.51)
(5, 5, 5)

• 
  роw (, ) – ni ga ko’tarish:
  

>>> math.pow(10, 2), 10**2, math.pow(3, 3), 3**3
(100.0, 100, 27.0, 27 )

• 
  fabs () – absolyut qiymat:
  

>>> math.fabs(10), math.fabs(-10) , math.fabs(-12.5)
(10.0, 10.0, 12.5)

• 
  fmod() – qoldiqli bo’lish:
  

>>> math.fmod (l0, 5) , 10%5, math.fmod (l0, 3), 10%3
(0.0, 0, 1. 0, 1)

• 
  factorial () – son faktoriali:
  

>>> math.factoria1(5), math.factorial(6)
(120, 720)

• 
  fsum ( ) - berilgan ro’yxatdagi barcha sonlar yig’indisini aniqlash:
  

> > > sum ([.1, .1, .1, .1, .1, .1, .1, .1, .1, .1])
0. 9999999999999999
>>> fsum ([ .1, .1 , .1 , .1 , .1, .1 , .1 , .1 , .1 , .1 ] )
1.0
