POWER_OF_FIVE_128 Cost and usage in rust core

I am struggling with minimizing my code size. While I was checking my code I found a ten kilobyte table here in core. First of all I am curious what's the goal of this table and how can I avoid it?

pub static POWER_OF_FIVE_128: [(u64, u64); N_POWERS_OF_FIVE] = [
    (0xeef453d6923bd65a, 0x113faa2906a13b3f), // 5^-342
    (0x9558b4661b6565f8, 0x4ac7ca59a424c507), // 5^-341
    (0xbaaee17fa23ebf76, 0x5d79bcf00d2df649), // 5^-340
    ...
