operator-=

UnitAlgebra& operator-=(const UnitAlgebra& v);
template <typename T> UnitAlgebra& operator-= (const T& v);

Subtract something from this UnitAlgebra. If the argument is a UnitAlgebra and the units do not match, an error will occur. Otherwise, if the value is unitless (e.g., an int), it will be subtracted from the value of this UnitAlgebra.

Parameters​

  • v (UnitAlgebra) value to subtract
  • v (typename T) value to subtract
  • returns (UnitAlgebra&) This UnitAlgebra after the subtraction operation.

Example​

SST::UnitAlgebra num0("8s");
SST::UnitAlgebra num1("5s");
num0 -= num1;
// num0 = 3s
