[fixed] fast_atof bug

[RVL]

The function parses negative exponents incorrectly. It doesn't take into account a possible '-' sign just before exponent value.
Current SVN:

Code: Select all

   85 		if (*c == 'e')
   86 		{
   87 			++c;
   88 			//float exp = (float)strtol(c, &t, 10);
   89 			float exp = (float)strtol10(c, t);
   90 
   91 			f *= (float)pow(10.0f, exp);
   92 			c = t;
   93 		}

Corrected variant:

Code: Select all

		if (*c == 'e')
		{
			++c;
			//float exp = (float)strtol(c, &t, 10);
			bool einv = (*c=='-');
			if (einv) c++;

			float exp = (float)strtol10(c, t);
			if (einv)
				exp *= -1.0f;

			f *= (float)pow(10.0f, exp);
			c = t;
		}

fixed in revision 702.

i recently reported a bug on wings3d regarding this, that the obj exporter exports doubles rather than floats.
i guess i should have looked closer to home first
