I want to implement following conditions for a variable g

g = 1 for T>1439

g= (T-1450)/100 for 1339>T>1439

g= 0 for T<1339

what is the syntax for writing the such statements?
can anyone please help?

The general syntax for conditional statements is if(condition,true_branch,false_branch). You can use two nested if()-calls to express the condition for g above. You can also use a piecewise function. This is more readable if there are many branches.

Thank you.

I used the piecewise function.
solved the problem.
