Milyan

Milyan waa tiro dhan 1,000,000, taasoo la mid ah kun kun (1,000 × 1,000). Nidaamka toban-saldhig ah (decimal) waxay leedahay hal iyo lix eber, waana 10 oo la kabay lixda jibbaar ah (10⁶). Ereyga Af-Soomaaliga ah ee "milyan" wuxuu ka soo jeedaa isla xididka ereyada Yurubiyaanka ah ee tirintan.

Milyan waxay kaalin muhiim ah ka ciyaartaa tirinta dadweynaha, xisaabaadka dhaqaalaha, iyo cabbiraadaha sayniska. Marka tirooyinku ka weynaadaan, waxaa la isticmaalaa bilyan iyo tirilyan, laakiin macnahoodu wuu ku kala duwan yahay nidaamyada kala duwan.

Qorista iyo calaamadaha

Milyan waxaa lagu qoraa 1,000,000 marka comma loo isticmaalo kala-soocidda kooxaha saddexda lambar, sida caadada Ingiriisiga. Luqado kale, sida Talyaaniga iyo Turkiga, waxay isticmaalaan dhibic (1.000.000) ama meel bannaan (1 000 000). Nidaamka SI (cabbirka caalamiga ah) horgale "mega-" ayaa loo isticmaalaa milyan, tusaale megawatt oo ah milyan wat.

Sifooyin xisaabeed

1,000,000 waa laba-jibbaar (square) tirada 1,000, sidaas darteed xididkeeda labaad waa 1,000. Kala-qaybiyayaasheeda koowaad waa 2 iyo 5 oo keliya, maadaama 1,000,000 = 2⁶ × 5⁶. Waa sidoo kale jibbaar lixaad oo 10 ah.

Kala duwanaanshaha nidaamyada tirinta

Milyan waa isku mid dhammaan nidaamyada caadiga ah. Kala-duwanaanshuhu wuxuu ka bilaabmaa tirooyinka ka weyn: nidaamka gaaban (short scale), oo lagu isticmaalo Ingiriisiga casriga ah, bilyan waa kun milyan (10⁹); nidaamka dheer (long scale), oo weli laga isticmaalo qaar ka mid ah dalalka Yurub, bilyan waa milyan milyan (10¹²).
