compiling error if (Value >=3.7 && <=3.9) { }

i am getting a compiling error

float Value = 0.0;

if (Value >=3.7 && <=3.9) {  }

exit status 1
expected primary-expression before ‘<=’ token

float Value = 0.0;

if (Value >=3.7 && ???  <=3.9) {  }

What needs to be less than 3.9? Value? You have to say.

Thankyou problem solved
