Got java.lang.IllegalArgumentException when using data provider pass in TestNG -

here part of data provider method:

@dataprovider (name = "dataprovider1") public static object[][] dataprovider1() {     return new object[][] {             // total sale 0.00             { new object[][]{{msoecommissioncalculator.replacemnet_item, 0.00},                     {msoecommissioncalculator.replacemnet_item, 0.00},                     {msoecommissioncalculator.replacemnet_item, 0.00},                     {msoecommissioncalculator.replacemnet_item, 0.00},                     {msoecommissioncalculator.consulting_item, 0.00},                     {msoecommissioncalculator.maintenance_item, 0.00},                     {msoecommissioncalculator.basic_item, 0.00},                     {msoecommissioncalculator.maintenance_item, 0.00}}, 0.00 }, 

when use data provider like:

    @test (dataprovider = "dataprovider1", dataproviderclass = msoecommissioncalculatortestdataprovider.class) public void testforprobationary(object[][] sales, float assertcommission) {  } 

this generates following error:

failed: testforprobationary([[ljava.lang.object;@380fb434, 0.0) java.lang.illegalargumentexception: argument type mismatch 

0.00 double, not float. use 0 or 0.00f instead.
