StringNumber is a decimal number type that stores the number as a string.
The "rules" that are followed for the implementation of StringNumber are:
- Only the string representation of the number may be stored, excluding local variables.
- For operations: no conversion from
StringNumberto a different type. Only one digit of the number may be converted at a time.
As you might expect, the benchmark results are horrible compared to those of f64.
test f64_add ... bench: 0 ns/iter (+/- 0)
test f64_sub ... bench: 0 ns/iter (+/- 0)
test f64_mul ... bench: 0 ns/iter (+/- 0)
test string_add ... bench: 135 ns/iter (+/- 3)
test string_sub ... bench: 187 ns/iter (+/- 14)
test string_mul ... bench: 972 ns/iter (+/- 5)
But this doesn't mean that StringNumber is completely useless. Here are some reasons why you might want to use StringNumber:
