Python math functions list available as standard in the Math module. You have to import the module using import math to use mathematical functions in Python.
Here is a List of Functions in the Python Math Module.
| Function | Description |
|---|---|
| ceil(x) | Returns the smallest integer greater than or equal to x. |
| copysign(x, y) | Returns x with the sign of y |
| fabs(x) | Returns the absolute value of x |
| factorial(x) | Returns the factorial of x |
| floor(x) | Returns the largest integer less than or equal to x |
| fmod(x, y) | Returns the remainder when x is divided by y |
| frexp(x) | Returns the mantissa and exponent of x as the pair (m, e) |
| fsum(iterable) | Returns an accurate floating point sum of values in the iterable |
| isfinite(x) | Returns True if x is neither an infinity nor a NaN (Not a Number) |
| isinf(x) | Returns True if x is a positive or negative infinity |
| isnan(x) | Returns True if x is a NaN |
| ldexp(x, i) | Returns x * (2**i) |
| modf(x) | Returns the fractional and integer parts of x |
| trunc(x) | Returns the truncated integer value of x |
| exp(x) | Returns e**x |
| expm1(x) | Returns e**x – 1 |
| log(x[, b]) | Returns the logarithm of x to the base b (defaults to e) |
