| Summary | 0000948: mfplain.mp defines a wrong round function | ||||
| Description | The last mfplain.mp version that I could find (% $Id: mfplain.mp,v 1.9 2005/04/28 06:45:21 taco Exp $) defines: vardef round primary u = u enddef; vardef hround primary x = x enddef; vardef vround primary y = y enddef; But this should probably be (according to the METAFONTbook): vardef round primary u = if numeric u: floor(u+.5) elseif pair u: (hround xpart u, vround ypart u) else: u fi enddef; vardef hround primary x = floor(x+.5) enddef; vardef vround primary y = floor(y.o_+.5)_o_ enddef; | ||||
| Steps To Reproduce | mpost '&mfplain \mode:=localfont; input font' where font.mf contains the following line: message decimal(round(4.2)); This will output 4.2 instead of 4 | ||||
| Additional Information | Taco Hoekwater had probably his reasons to do so. Probably one should ask him before changing mfplain.mp. | ||||
| Tags | No tags attached. | ||||

Thank you very much. I will see asap. |

Taco says """ there is no rounding in mp because it is not needed mf rounds because of the bitmap grid at least that was JDH's take on it """ I will leave unmodified these functions, perhaps I cann add MFround etc. |
