Python math library | isfinite() and remainder() method

Python has math library and has many functions regarding to it. math.remainder() method returns an exact (floating) value as a remainder. Syntax:

math.remainder(x, y)

Time Complexity: O(1)

Auxiliary space: O(1)

For finite x and finite nonzero y, this is the difference x – n*y, where n is the closest integer to the exact value of the quotient x / y. If x / y is exactly halfway between two consecutive integers, the nearest even integer is used for n. The remainder r = remainder(x, y) thus always satisfies abs(r) <= 0.5 * abs(y). 

Python3




# Importing Math module
import math
 
# printing remainder of two values
print(math.remainder(5, 2))
print(math.remainder(10, 5))
print(math.remainder(12, 7))
print(math.remainder(6, 2))


Output:

1.0
0.0
-2.0
0.0

 

math.isfinite() function –

Syntax:

math.isfinite(x)

Time Complexity: O(1)

Auxiliary space: O(1)

math.isfinite() method returns True if x is neither an infinity nor a NaN, and False otherwise. (Note that 0.0 is considered finite.) 

Python3




# Importing Math module
import math
 
# printing remainder of two values
print(math.isfinite(5))
print(math.isfinite(float('nan')))
print(math.isfinite(-2.5))
print(math.isfinite(0.0))


Output:

True
False
True
True
