and strings.

dec64_math.c is a placeholder implementation of elementary functions. Many of these function are not accurate enough or fast enough. It should be replaced with a better implementation. The functions include
acos asin atan atan2 cos exp factorial
log raise root sin sqrt tan
and
random seed
