Sorry Kat,
Early morning is not a good time for making sense.
What i'm saying is a floating point number is stored in two parts
1. the mantissa
2. the exponent
an example is the 0.1 is stored as 1 x 10^-1
thus the mantissa is 1 and the exponent is -1
so using a 8-bit float as an example 0.1 in binary is
0001 and 1111(-1 in 2's complement)
So storing numbers like 0.1, 0.3 and 0.01 completely accurately should
not be a problem. It is only a problem in 'larger' decimal numbers.
for i = 31.4 to 31.5 do... should work perfectly. Or am I just been
dumb?
