I have the following function to compare two floating points int compare(float f1, float f2)
{ float epsilon = 0.00001; long float diff = fabs(f1 - f2); if (diff < epsilon) return 0; else if (f1 > f2) return 1; else return - 1; } but when compiling I get an error: In function 'int compare(float, float)':
error: 'long' specified with 'float' 60 | long float diff = fabs(f1 - f2); This used to work in the past and if anyone has any idea what I am doing wrong here I will be happy to get an advice Thanks! Date Time Of Last Edit: 2021-02-12 11:49:27

Remove the long from the following - long float diff = fabs(f1 - f2);
long float is not a built-in type in c++ - https://en.cppreference.com/w/cpp/language/types |

Hi, for price comparison inside your SC studies better to use built-in sc.FormattedEvaluate function.
