Ultimately, I want to define a bunch of c array later in the file. Since C requires the array length to be compile time constant, my attempt as follows:
DEF SIZE = 20
DEF SIZE2 = SIZE * SIZE
DEF PERIOD_SIZE = 20
# 8000
DEF SIZE3 = PERIOD_SIZE * SIZE2
DEF SIZE_COEF = 20
# 160000
DEF SIZE4 = <long> SIZE3 * SIZE_COEF # Error
I wish to use int
everywhere exept for SIZE4
because it may cause overflow in some platform. However I am not able to cast since Cython doesn't seem to support the syntax.
What is the best way to define SIZE4
apart from to write it explicitly like: DEF SIZE4 = 160000
