I am using srtmreader class. When I set coordinates to

(-23.4,34.3)
_latitude_secs = -46.399999999999999

and in readHeight() function

unsigned temp_row = (unsigned) round(_latitude_secs *3600/3); where temp_row is expected be row number in binary file but its value is 4294911616in 1201*1201file.

Thank you for reporting this, it is likely there is bug in the math code which converts the coordinates. I will investigate this issue. Tracking it under the other repository.
