howdy, check the attached patch.
1e+06 + 1 is not equal to 1e+06
but 1e+09 + 1 is equal to 1e+09
meaning it didn't add 1 to 1e+09! Meaning there's a limit where it stops adding 1 to something.
how's that and why?
it's a limitation of 32 bit float. since 1 bit is used for the sign, 8 for the exponent, 23 bit are left for the significant. this mean that you can't have more precision in the significant than 2^24 -1 (a bit less than 1.7*10^7)
