Inconsistencies in float/string vs int/string comparisons

Comparisons between string
values and float
values behave differently than those between string
values and int
values.
More precisely, int
values can reliably compared to string
values, as the implicit conversion is performed correctly. However, this is not the case for float
values. This is due to the usage of sprintf
to perform the conversion (for example, lines 185-189 of src/buzz/buzztype.c).
Code to reproduce:
function init() {
log(-9 == "-9") # Result: 1
log(-9.0 == "-9.0") # Result: 0
log(-9 == -9.0) # Result: 1
}
Associated test suite: TEST(BuzzObjCompare, String) in src/testing/unittest/buzztype_test.cpp (instructions on how to run the tests are provided in src/testing/unittest/README.md).
