math 0.1.0 on Edge Python

math

math works like Python’s. It holds the constants, the float functions, the integer functions and the exact sums, and fsum, hypot and dist give Python’s results to the last bit.

import math

print(math.sqrt(2), math.pi)
print(math.hypot(3, 4, 12), math.dist((0, 0), (3, 4)))
print(math.floor(2.7), math.ceil(2.1), math.trunc(-2.7))

Output

The integer functions take ints and stay exact, and prod keeps a product of ints an int.

import math

print(math.factorial(20), math.comb(10, 3), math.perm(5, 2))
print(math.gcd(12, 18, 24), math.lcm(4, 6), math.isqrt(99))
print(math.prod([1, 2, 3, 4]), math.prod([0.5, 4]))

Output

fsum adds exactly and rounds once, isclose compares within a tolerance, and modf and frexp split a float into a tuple.

import math

print(0.1 + 0.2 + 0.3, math.fsum([0.1, 0.2, 0.3]))
print(math.isclose(0.1 + 0.2, 0.3), math.isclose(1.0, 1.001, rel_tol=0.01))
print(math.modf(3.75), math.frexp(12.0))

  }
}

True True
(0.75, 3.0) (0.75, 4)

Output

A value outside a function’s domain raises ValueError, and a result too large for a float raises OverflowError. Ints hold 128 bits in Edge, so an integer result past that, such as factorial(34), raises OverflowError too. nextafter, ulp and sumprod are not supported.

import math

for f, x in [(math.sqrt, -1), (math.exp, 1000)]:
    try:
        f(x)
    except (ValueError, OverflowError) as e:
        print(type(e).__name__, e)
