fixed a_GetCVarFixed(str name)
Returns the value of an int or float CVar as a fixed-point number.
Returns 0 if the CVar doesn't exist or is not a number.
The function works by calling GetCVarString and parsing the text with atof.
int mul = a_GetCVarFixed("mymod_multiplier"); // declared as float in CVARINFO
int value = FixedMul(x, mul);
From UpdateCursor source:
int sensitivity = a_GetCVarFixed("mouse_sensitivity");
int speedX = FixedDiv(CursorSpeedX, FixedMul(a_GetCVarFixed("m_yaw"), sensitivity));
int speedY = FixedDiv(CursorSpeedY, FixedMul(a_GetCVarFixed("m_pitch"), sensitivity));
