Basic Math Functions of math Module in Python

Method Description
ceil() This method rounds the specified number up to the nearest integer.
comb() This method method returns the number of ways by which k items from n items can be chosen without giving importance to repetition and order.
copySign() This method returns a number with magnitude of the first argument and sign of the second argument.
fabs() This method returns the absolute value of the specified number.
factorial() This method returns factorial of the specified integer.
floor() This method rounds the specified number down to the nearest integer.
fmod() This method computes the remainder or the modulo operation on two arguments.
frexp() This method returns mantissa and exponent of the specified number.
fsum() This method computes and returns an accurate sum of floating point values in an iterable.
gcd() This method returns the highest common factor or the greatest common divisor of the specified arguments.
isclose() This method checks if the two specified values are close to each other. If they are, it returns True, otherwise, False.
isfinite() This method checks if the specified argument is neither an infinity nor a NaN. If it is not, True is returned, else False is returned.
isinf() This method checks if the specified argument is positive or negative infinity. If it is, True is returned, otherwise, False.
isnan() This method checks if the specified argument is a NaN which stands for not a number. If it is, True is returned, otherwise, False.
lcm() This method computes and returns the least common multiple of the specified arguments.
Idexp() Idexp(x,y) returns x*2^y.
modf() This method returns integral and fractional parts of the specified number.
nextafter() This method returns next floating-point number after the first specified number towards the second specified number.
perm() This method method returns the number of ways by which k items from n items can be chosen without repetition and with order.
prod() This method returns the product of all the elements of the input iterable.
remainder() This method computes the remainder operation on the two specified arguments as per the IEEE 754 standard.
trunc() This method returns the truncated integer part of the specified argument.
ulp() This method returns the least significant bit of the floating-point number argument.
