Mayelana nalolu hlelo lokusebenza

Bhala izibalo zakho ngendlela ocabanga ngayo. Qeda noma yimuphi umugqa ngo-"=" bese
impendulo ivela khona manjalo, khona kanye kunothi lakho.

■ Kungokwemvelo njengokucabanga
Akukho ukushintshela ku-calculator, akukho ukukopisha nokunamathisela. Uhlu lokuthenga,
ukuhlukaniswa kwezikweletu, isabelomali, ukuhlolwa okusheshayo kobunjiniyela — bhala bese
ubala endaweni eyodwa. Shintsha inombolo, zonke izibuyekezo zemiphumela zibukhoma.

■ Iziguquguquko ziphilisa amanothi
Chaza kanye: ikhofi = 4.5
Sebenzisa noma kuphi: ikhofi × 5 = 22.5
Hlela incazelo bese konke kubalwa kabusha.

■ I-calculator eyakhelwe ngaphakathi
I-calculator ehlanzekile, ejwayelekile yemisebenzi emine enephesenti elihlakaniphile
(100+5%=105), ukuguqula uphawu, kanye nokuphindaphinda okuhlakaniphile.
Ukubuka kuqala komphumela obukhoma (okumpunga okukhanyayo) okuboniswe ngenhla kokufaka; thepha ⌫ ukuze ususe idijithi.

Ngemva kokucindezela =, umphumela uvela ngemuva nje kophawu lokulingana kanye nokubuka kuqala
kuyanyamalala — thayipha idijithi entsha ukuqala ukubala okusha.

cindezela = ngokuphindaphindiwe ukuze uqhubeke (5 + 3 = = = → 8, 11, 14),
noma cindezela = ngemuva nje komqhubi ukuze uphinda i-operand yokugcina (5 + = → 10).

■ Izibalo ezigcwele, khona kanye kumanothi akho
Thayipha `rent + coffee × 30 =` bese impendulo ivela ngombala ophuzi
ngokushesha. Izibalo, ama-parentheses, amaphesenti (20 + 20 × 15% = 23)
konke kusebenza emgqeni njengoba ubhala.
Izibalo zobunjiniyela zilula ngokufanayo: trig ngamadigri (sin(30°) noma sin(deg(30)) = 0.5),
imisebenzi yesayensi (sqrt/sin/cos/tan/asin/exp/ln/log2/hypot/mod/cbrt…),
kanye nokuguqulwa kweyunithi (100 km → mi, 25 °C → °F). Imiphumela emikhulu kakhulu noma emincane kakhulu
ishintshela ku-scientific notation ngokuzenzakalelayo.

■ Umhlahlandlela wendlela yokwenza izinto owakhelwe ngaphakathi
Awuqiniseki ukuthi uzoqala kuphi? Isikrini sezilungiselelo → Mayelana manje sihlanganisa
Umhlahlandlela othi "Indlela yokusebenzisa amanothi" ohlanganisa ukubalwa okuqondile = ukubalwa, imisebenzi yesayensi,
ama-engeli kanye neziguquguquko zemigqa ehlukene — yivule bese uzama.

■ Ilungele ukusetshenziswa ekuqalisweni kokuqala
Amanothi ayishumi agcwaliswe kusengaphambili (isabelomali sanyanga zonke, ukwahlukaniswa kwesidlo sakusihlwa,
ukwabelana ngezindleko zohambo, ukusetshenziswa kwekhofi…) thumela ngohlelo lokusebenza. Shintsha inombolo
ukuze ubone ukuthi "amanothi + isibali" asebenza kanjani — noma vele uwasuse.

■ Kungani u-$7?
Ngoba ungumthengi, hhayi umkhiqizo:
• Azikho izikhangiso — nanini
• Akukho ukulandelela — uhlelo lokusebenza aluceli izimvume ze-ZERO, ngisho ne-inthanethi
• Azikho ama-akhawunti — idatha yakho ayiphumi kudivayisi yakho
• Azikho izinto ezithengiwe ngaphakathi kohlelo lokusebenza — khokha kanye, gcina unomphela

■ I-Android Yesimanje
Hlanza izingqikithi ezikhanyayo nezimnyama ngezici ezinhle kakhulu zemiphumela e-orenji, ungaxhunyiwe ngokuphelele ku-inthanethi,
ukusekela ngokulondoloza uhlelo kanye nokusekelwa kokudluliselwa kwedivayisi. Usayizi wefonti womzimba wamanothi uyalungiseka
(14–30) futhi usebenza ngokushesha.

Ipeni, ikhasi, impendulo. Lokho kulula.

Yini entsha

What's new in v1.4.19:
• Fewer meaningless units are shown — two refinements to the "hide unreasonable dimensions" rule:
- Composite units: in addition to two or more components with |exponent| ≥ 3 (such as m³/s³), a unit is now also hidden when one component is ≥ 3 while another is ≥ 2 — for example m³/s² and m²/s³. Standard units in which the high exponent stands alone are unaffected: m³/s (flow rate), mol/m³ (molar concentration), m/s³ (jerk), kg/m³ (density).
