설명

Each is spelled the same way in WGSL and GLSL and evaluated the same way by the CPU backend. On floats % is a truncating remainder, so its sign follows the dividend: WGSL’s native % behaves this way, and the GLSL backend writes a - b * trunc(a / b) because GLSL ES 3.00’s own % is integer-only. When a negative operand is possible and a floor modulo is wanted, use mod, which is floor-mod on every target; the .mod() method on Node emits this truncating %. For integer operands the CPU backend follows WGSL: two’s-complement wrap, truncating / with x / 0 = x and x % 0 = 0, and <</>> as logical shifts on u32, with >> on i32 an arithmetic (sign-preserving) shift.
