Tatara::FloatVector

About

Tatara::FloatVector is Vector class like static type programming lang.

Tatara::FloatVector use Float value. But, you can use Integer for value.

@f = Tatara::FloatVector.new
@f[0] = 4.2
# => Set value 4.2 for index of 0.
@f[1] = 8
# => Set value 8.0 for index of 1.

But, can not use String for value.

@f = Tatara::FloatVector.new
@f[0] = "42"
# => Error!
