It helps if you look at it in binary. First of all, as you know, negative numbers are expressed as (highest possible unsigned number plus 1 minus value). So -1 in a 16-bit integer, which has the highest unsigned value of 65535, would be 65536-1=65535, i.e. 0xffff in hex, or 1111 1111 1111 1111 in binary.

WebThis can be simplified to (~ (x >> 1) + x) >> 31. Assuming x is signed, need to return 0 for any number not zero, and 1 for zero. A right shift on a signed integer usually is an arithmetical shift in most implementations (e.g. the sign bit is copied over). Therefore right shift x by 31 and its negation by 31. WebLogical NOT results in a true if the operand is false and vice versa. Example Code This operator can be used inside the condition of an if statement. if (!x) { // if x is not true // statements } It can be used to invert the boolean value. x = !y; // the inverted value of y is stored in x ※ NOTES AND WARNINGS:
