v0.2.4-beta

Type conversion for floats, sin and cos for f32, figured out range slicing

math/cos([0.0 0.0])
math/cos(0.0)
math/sin(1.5707963267948966)
math/sin([1.570796327 1.570796327])
x := [1 2 3; 4 5 6; 7 8 9]; x[2..=3, 2..=3]
a := [1,2;3,4]; a[1,2]
false != true
x<f32> := 123;
2<u8> ^ 2<u8>
2.0 ^ 2.0
