problem here

this method aint working how its supposed to. It works for most cases, but not all for some reason. also not for -+ and -- max value what ever that shoudl mean. The following test cases are failing (also i cant use if statements, dont ask why :/): Test Case · decryptFloat - RandomPositives failed Some positive values seem to produce wrong number triplets Test Case · decryptFloat - RandomNegatives failed Some positive values seem to produce wrong number triplets Test Case · decryptFloat - +MAX_VALUE failed Did you consider all values? Test Case · decryptFloat - -MAX_VALUE failed Did you consider all values? public String decryptFloat(float fx) { //float adjustedFx = (fx == Float.MAX_VALUE fx == Float.MIN_VALUE) ? Float.NaN : fx; float value = (fx + mbox.getIntHint()) * mbox.getFloatHint(); //float adjValue = (value == Float.MAX_VALUE value == Float.MIN_VALUE) ? Float.NaN : value; double value1 = Math.abs(Math.cos(value)); value1 = Math.max(-1.0, Math.min(1.0, value1)); String value3 = String.format("%.3f", value1); String value4 = value3.replaceFirst("^0\.0*", ""); String value5 = value4.substring(value4.indexOf(".")+1); return value5; }

Please format your code to make it more readable. For java, it should look like this:

```java
public void foo() {
 
}
```

```java
public void foo() {
 
}
```

What is the method supposed to do? and what exactly doesn't work?

LordBeerusOP•3w ago

the test cases that dont work are up there

dan1st•3w ago

these are just partial descriptions not full test cases describing what the exact inputs and expected outputs are

LordBeerusOP•3w ago

its supposed to get a float fx, add an int to it, then multiply by a float, then take cos of that value, then absolute value, then round to 3 decimal places and return those 3 decimal places. exactly, that my problem 😭 these "errors" are all i have

dan1st•3w ago

Why do you have the thing with Math.min and Math.max there? We can't guess what you should do

LordBeerusOP•3w ago

its supposed to make sure the value statys within those boundaries in summary, there are certain floats that dont give me the right answer. chatgpt says causes could be how MINValue and MAXValue values are handled, rounding errors and that the number after the initial multiplication is too large but i have no idea how to correct that without an if loop. thats what the min max methods are for

dan1st•3w ago

It isn't a comment

LordBeerusOP•2w ago

shits impossible nvm got it
