// RADIX^2 TABLES
// --------------
// Conditionally compile the pre-computed radix**2 tables.
// These tables take `2 * (value % (radix^2))`, and return
// two consecutive values corresponding to both digits.
//
// Total array storage:
// Without radix: ~430 B:
// 200 u8
// 11 f32
// 23 f64
// With radix: ~55 KB.
// 32210 u8
// 518 f32
// 2610 f64
// Provides ~5x performance enhancement.
//
// These arrays are cache-friendly, for each BASE[2-36] table,
// elements can be access sequentially 2-at-a-time, preventing as many
// cache misses inside inner loops. For example, accessing the two elements
// for a remainder of `3` for the radix^2 in radix 2 will give you `1` and `1`,
// at indexes 6 and 7.
