C++11 constexpr compilation error

I am trying to declare a constexpr and it throws compilation errors.

static constexpr float goBaseMovementSpeed = (1.135f / 440.f);

Why is this line not working?

error C2144: syntax error : 'float' should be preceded by ';'

error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

goBaseMovementSpeed is a member of a class.
