Just want to know whether the casts in the example below are redundant.
uint16_t basic_units = 4587U;
uint8_t int_val = (uint8_t) (((uint16_t ) (basic_units * 5U)) / 1000U);

The
uint8_tcast is redundant. Theuint16_tcast may have the (un)intended consequence of truncating an intermediate value in the calculation ifbasic_units * 5Uwould overflow a normaluint16_tbefore being divided by 1000.
