此错误应如何修改？

error:invalid types 'float' ' for array subscript

float propensity_granularity(float a, float b, float c)
{
    float table =
    {
      {{0.0,0.0,0.0}, {0.0,0.0,0.1}, {0.1,0.1,0.2}},
      {{0.1,0.1,0.2}, {0.2,0.3,0.4}, {0.4,0.5,0.6}},
      {{0.4,0.5,0.6}, {0.5,0.6,0.7}, {0.8,0.9,1.0}},
      {{0.9,0.9,1.0}, {1.0,1.0,1.0}, {1.0,1.0,1.0}}
    };
        return table;
}

下标索引不能是float类型，应该用unsigned int

把table443前边的float改成unsigned int还是报错啊。小白一个，求指教

他说的是括号里的形参a,b,c
