Question

Can Somebody please tell me what is wrong. when I type the equations for low and high into a calculator I get low = 118.129 high = 113.629.
But for some reason both low and high are showing 119.0 when I run the code.

match_FRC = 82;//Double.parseDouble(FRC_match_textbox.getText().toString());
match_DTR = 1.455;//Double.parseDouble(DTR_match_textbox.getText().toString());

//math functions 
low = Math.round((match_FRC * match_DTR)/((1/100)+1));
high = Math.round((match_FRC * match_DTR)/((5/100)+1));

Answer 1

You need to use a floating point constant instead of integers, e.g.:

low = Math.round((match_FRC * match_DTR)/((1.0 / 100)+1));

As it is, your ((1 / 100) + 1) is an integer expression that evaluates to exactly 1.

Making the 1 into 1.0 (or the 100 into 100.0) will cause promotion of the other operands (and the expression as a whole) into floating point.
