P0926GW has only 6 significant digits before and after the decimal point. When the given float’s significant digits are converted to characters within 6 bits, there will be no loss of precision. However, when the significant digits are greater than 6 bits, there will be a loss of precision.

·The significant digits before and after the decimal of a double are only 16. When the given double is converted to a string within 16 significant digits, there will be no loss of precision. However, when the significant digits are greater than 16, there will be a loss of precision.

·P0926GW: When determining that floating-point numbers are equal, we recommend using a range to determine. If x is within a certain range, we consider it equal. As for how to define the range, it depends on the actual situation. Floats and doubles are different.

For example, to determine whether floating point numbers floatA and B are equal, we calculate float x=A – B;

And set const float EPSINON=0.00001;

if ((x >= – EPSINON)&& (x <= EPSINON); // Or if (abs (x)<=EPSINON)

Cout<<“A is equal to B<<endl< span=””></endl;<>
