''fixed a_GetCVarFixed(str name)''

<note important>This function is called ''a_GetCVarFixed()'' because it conflicts with [[:GDCC]]'s unrelated ''GetCVarFixed()''.</note>

===== Description =====
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 [[zdoom>GetCVarString]] and parsing the text with [[atof]].

===== Examples =====
<code>
int mul = a_GetCVarFixed("mymod_multiplier"); // declared as float in CVARINFO
int value = FixedMul(x, mul);
</code>

From [[UpdateCursor]] source:
<code>
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));
</code>
