Returns the middle of three numbers. Also useful for clamping.
- The first number.
- The second number.
- The third number.
This function is designed simply to give you the middle value out of three.
However, one of its best uses is frequently overlooked: it can clamp a value to a range.
If you call
mid(min_val,val_to_clamp,max_val), it acts exactly like the similarly-formatted
clamp() function in other languages. The result will be
min_val if val is too low,
max_val if val is too high, and
val itself if it is in range.
print(mid(8, 2, 4)) -- 4 print(mid(-3.5, -3.4, -3.6)) -- -3.5 print(mid(6, 6, 8)) -- 6 -- clamp to 0..1 print(mid(0, v, 1)) -- sort three values v0 = min(min(a,b),c) v1 = mid(a,b,c) v2 = max(max(a,b),c)
