Suppose there are two float numbers: a, b. I need to assign value of a to b. Then b would be converted to a text string by a function, which I can not change. Convertion is done by taking first 3 decimal digits of a float number without rounding, other points are ignored. This leads to loss of accuracy.
Question: how can I change value of a so, that then after convertion b would be like if it was rounded?
Hope that I managed to explain problem, but if didn`t, please, tell me.
I think that these function use "truncate": 1.2346 => 1.234, right?
You can add 0.0005
b = a + 0.0005
Example:
Round to lower
a = 1.2341;
b = a + 0.0005; // 1.2346
string result = yourfunction(b); // 1.234
Round to upper
a = 1.2346;
b = a + 0.0005; // 1.2351
string result = yourfunction(b); // 1.235
