Errors relating to math module

[swamishiju]

Currently the integration test for the math module doesn't work I have compiled a list of issues that cause this

• [x] Kwargs are not supported in general (in is_close specifically)
• [ ] Functions returning non trivial data types (modf, frexp) which are then assigned to a variable

Another error i found while testing is

• Functions returning non trivial data types which are not assigned to anything or passed into functions

Simplest replication code for each

def f(x: i32 = 0):
    print(x)

def f() -> list[i32]:
    return [1,2]

x: list[i32]
x = f()

def f() -> list[i32]:
    return [1,2]

f()

The only cases in which function returning lists and tuple are not a headache is when we use it as input to some function
