bitset expression function

Sets or clears a bit in a number.

Since 18.5

bitset(number, bit_index, value)

Returns the provided number with the bit corresponding to bit_index being either set if value is not zero, or clear if value is zero.

All operands are rounded to the nearest integer before processing.

Bit 0 corresponds to the rightmost bit. Negative bit indices, or bit indices over 63, will return the number unchanged.


bitset (0, 3, 1) = 8
bitset (15, 3, 0) = 7
