i feel like an idiot asking this.. but in the blizzard.j it is like this: x-(x/y)*y well i've been racking my brain.. and if you follow order of operations you always get 0.. 10-(10/4)*4 = 10-10 = 0.. so someone come tell me how stupid i am (nicely) then what i'm doing wrong and/or how wc3 order of operations is. cause ive tried everything even other than normal order of operations. |

wow.. heh.. i hate integer division, it should die. no one likes it. but thanks. i'm guessing in like real math (non-wc3) they use integer division for this also? |

from blizzard.j Code:
//===========================================================================
// Calculate the modulus/remainder of (dividend) divided by (divisor).
// Examples: 13.000 mod 2.500 = 0.500. -6.000 mod 2.500 = 1.500.
//
function ModuloReal takes real dividend, real divisor returns real
local real modulus = dividend - I2R(R2I(dividend / divisor)) * divisor
// If the dividend was negative, the above modulus calculation will
// be negative, but within (-divisor..0). We can add (divisor) to
// shift this result into the desired range of (0..divisor).
if (modulus < 0) then
set modulus = modulus + divisor
endif
return modulus
endfunctionThey convert it to an integer, so it is integer division too |
