Cant use decimal values in a call function?

[nidh0gg]

Im currently using C, and when i try to call functions with decimals it doesn't let me do so and just changed the numbers into some crazy big random value.

Calling the function

            //First value = X, Second Value = Y, Third Value = Width, Fourth Value = levels
            Mickey(0,0,0.25,5);

The function
(when i use debugging, when it calls itself again it spits out absurd numbers for x, y, and level and width becomes 0, HOWEVER if i use whole numbers when calling the function it works properly)

void Mickey(x1 ,y1 ,width1 ,level)
{
    float x, y, width;
    width=width1;
    x=x1;
    y=y1;

    if(level >= 1)
    {
        glBegin(GL_QUADS);                      // Draw A Quad
        glColor3f(0.25f,0.25f,0.25f);
        glVertex3f(x,         y,       0.0f);              // Top Left
        glVertex3f(x + width, y,       0.0f);              // Top Right
        glVertex3f(x + width, y-width, 0.0f);              // Bottom Right
        glVertex3f(x,         y-width, 0.0f);              // Bottom Left
        glEnd();                                // Done Drawing The Quad

        Mickey(x - (0.5 * width), y + (0.5 * width), width, level--); //Left Ear
        Mickey(x +        width , y + (0.5 * width), width, level--); //Right Ear
    }
}

// void Mickey(x1 ,y1 ,width1 ,level)
void Mickey( float x , float y , float width , int level )
{
    /*
    float x, y, width;
    width=width1;
    x=x1;
    y=y1;
    */

    if(level >= 1)
    {
        glBegin(GL_QUADS);                      // Draw A Quad
        glColor3f(0.25f,0.25f,0.25f);
        glVertex3f(x,         y,       0.0f);              // Top Left
        glVertex3f(x + width, y,       0.0f);              // Top Right
        glVertex3f(x + width, y-width, 0.0f);              // Bottom Right
        glVertex3f(x,         y-width, 0.0f);              // Bottom Left
        glEnd();                                // Done Drawing The Quad

        Mickey(x - (0.5 * width), y + (0.5 * width), width, level--); //Left Ear
        Mickey(x +        width , y + (0.5 * width), width, level--); //Right Ear
    }
}

Consider using double as the default floating-point type.

You haven't specified a type in your function. C will assume that these are int if an error isn't thrown.

Change line 1 to:
void Mickey( float x1, float y1, float width1, int level);

Did you read JLBorges's post? Particularly lines 4 to 9?

Just tried changing it to JLBorge's and i get this error

It looks like you pass an uninitialized variable into Micky's 4th parameter. With the debugger, put a breakpoint at the initial call of that function and check the value of the variable going into the 4th parameter.

At the intial call of function the value of the variables are:
X = 0
Y = 0
width = 0 (should be 0.5)
level = 1071644672 (should be 5)

-edit-

fixed it
