TO fix the last confirmations

1) gcc -O2  minified_to_string_radix.i -o 507 -lm && ./507
1e+23.toString(36) = ga894a06ac80000
ERROR expected "ga894a06abs0000"

2) gcc -O1  minified_to_string_radix.i -o 507 -lm && ./507
1e+23.toString(36) = ga894a06abs0000
OK

3) gcc -O1 -ffast-math minified_to_string_radix.i -o 507 -lm && ./507
1e+23.toString(36) = ga894a06abs0000
OK

4) gcc -O1 -fstrict-aliasing minified_to_string_radix.i -o 507 -lm && ./507
1e+23.toString(36) = ga894a06abs0000
OK 

5) removing inlined floor() fixed the issue

6) clang-6.0  -O2  minified_to_string_radix.i -o 507 -lm && ./507
1e+23.toString(36) = ga894a06abs0000
