Module step 

Available on crate features parse-floats or parse-integers or write-floats or write-integers only.

The maximum digits that can be held in a u64 for a given radix without overflowing.

This is useful for 128-bit division and operations, since it can reduces the number of inefficient, non-native operations.

Generation

See etc/step.py for the script to generate the divisors and the constants, and the division algorithm.

Functions

max_step

Get the maximum number of digits that can be processed without overflowing.

min_step

Get the number of digits that can be always processed without overflowing.

u64_step

Calculate the number of digits that can be processed without overflowing a u64. Helper function since this is used for 128-bit division.
