Obtains the fraction, which corresponds to a specific resource id, from a context's theme. If
the given resource id is invalid, a {@link NotFoundException} will be thrown.

@param context
The context, which should be used, as an instance of the class {@link Context}. The
context may not be null
@param resourceId
The resource id of the attribute, which should be obtained, as an {@link Integer}
value. The resource id must corresponds to a valid theme attribute
@param base
The base value of this fraction as an {@link Integer} value. A standard fraction is
multiplied by this value
@param pbase
The parent base value of this fraction as an {@link Integer} value. A parent fraction
(nn%p) is multiplied by this value
@return The fraction, which has been obtained, as a {@link Float} value
