What's the right way to parseFloat in Java

Question

I notice some issues with the Java float precision

       Float.parseFloat(\"0.0065\") - 0.001  // 0.0055000000134110451
       new Float(\"0.027\") - 0.001          


        

Answer 1

I would convert your float to a string and then use BigDecimal.

This link explains it well

new BigDecimal(String.valueOf(yourDoubleValue));

Dont use the BigDecimal double constructor though as you will still get errors
