If statements on negative decimal values ranges

Question

I am quite new to C# and I want to do an if condition on a number range of a negative value eg if(percentage is equals to -60 to -80 ) then DoWork, my question is , How do I check using an if statement, as switches doesn't allow checks on decimal values. -60 to -80 means (negative 61 up till negative 81) as my condition, how can I achieve this in C#, any help will be greatly appreciated ,like I said I am still new to the .Net world.

Answer 1

if(value >= -80 && value <= -60) {
  doWork();
}

Answer 2

I'm guessing when you say 'decimal value ranges' and percentages, you're doing the calculation, so in that case:

if( x >= -.81 && x <= -.61) { //do something }

otherwise, it would be:

if( x >= -81 && x <= -61) { //do something }

Answer 3

if(number >= -80.0f && number <= -60.0f)
{
     // Do stuff
}

Answer 4

if(a >= -80 && a <= -60) {
  DoWork();
}
