math Module Functions¶math module defines functions for performing various common mathematical calculations. import math
math.sqrt(900)
math.fabs(-10)
math module functions are summarized below| Function | Description | Example |
|---|---|---|
ceil(x) |
Rounds x to the smallest integer not less than x | ceil(9.2) is 10.0, ceil(-9.8) is -9.0 |
floor(x) |
Rounds x to the largest integer not greater than x | floor(9.2) is 9.0, floor(-9.8) is -10.0 |
sin(x) |
Trigonometric sine of x (x in radians) | sin(0.0) is 0.0 |
cos(x) |
Trigonometric cosine of x (x in radians) | cos(0.0) is 1.0 |
tan(x) |
Trigonometric tangent of x (x in radians) | tan(0.0) is 0.0 |
exp(x) |
Exponential function ex | exp(1.0) is 2.718282, exp(2.0) is 7.389056 |
log(x) |
Natural logarithm of x (base e) | log(2.718282) is 1.0, log(7.389056) is 2.0 |
log10(x) |
Logarithm of x (base 10) | log10(10.0) is 1.0, log10(100.0) is 2.0 |
pow(x, y) |
x raised to power y (xy) | pow(2.0, 7.0) is 128.0, pow(9.0, .5) is 3.0 |
sqrt(x) |
square root of x | sqrt(900.0) is 30.0, sqrt(9.0) is 3.0 |
fabs(x) |
Absolute value of x—always returns a float. Python also has the built-in function abs, which returns an int or a float, based on its argument. |
fabs(5.1) is 5.1, fabs(-5.1) is 5.1 |
fmod(x, y) |
Remainder of x/y as a floating-point number | fmod(9.8, 4.0) is 1.8 |
