Who can join coding classes across Adh Dhahirah?
Modern Age Coders teaches learners aged 6 to 67, including beginners, school students, university learners and working adults across Adh Dhahirah. Placement depends on observed ability, pace and objective rather than wilayat or age alone. The free first class uses an ability-matched task to identify a suitable course and format.
What is the Adh Dhahirah precision-loss project?
The learner adds two wholly synthetic integer batches: 9,007,199,254,740,991 and 2. Their exact total is 9,007,199,254,740,993. A JavaScript Number cannot represent that integer exactly and produces 9,007,199,254,740,992. The repair validates the safe range and uses BigInt, a database integer type or an exact decimal representation end to end.
Why can JavaScript Number lose a unit?
JavaScript Number uses binary floating-point. Consecutive whole numbers are exactly representable only through 9,007,199,254,740,991, which is Number.MAX_SAFE_INTEGER. Beyond that boundary, adjacent integers can map to the same machine value, so arithmetic and equality checks may silently stop distinguishing them.
How does the learner preserve an exact large total?
The learner receives the value as a string or another exact transport representation, validates its integer syntax and range, converts it to BigInt for integer arithmetic, stores it in an exact database type, and serializes it without coercing it back to Number. Tests cover the safe boundary, additions, round trips and displayed output.
Are the large aggregate and batch values official regional data?
No. Every large integer, batch label, calculation and error in the classroom tables is synthetic. Official sources are cited only for public administrative, geographic, infrastructure and development facts. The exercise does not measure actual mines, water networks, dams, facilities, residents, production or investment in Yanqul, Dhank, Ibri or elsewhere.
Does Modern Age Coders have a physical centre in Adh Dhahirah?
No Adh Dhahirah office or classroom is claimed. Lessons are live online. A learner joins with a laptop or desktop, stable internet, audio and a current browser. The teacher explains, observes work, reviews code and gives feedback synchronously. This page describes regional service availability rather than a local branch.
Can learners outside Ibri join these online classes?
Yes. Learners in Yanqul, Dhank and elsewhere in the governorate may request a class, subject to course and time availability. The service does not require travel to Ibri. A suitable computer, stable internet and working audio are required.
How much do coding classes in Adh Dhahirah cost?
The first class is free. Standard group tuition is USD 100 per month for two live lessons each week, normally eight lessons monthly. Standard private tuition is USD 150 per month for one learner with one teacher on the same usual frequency. Course, format, recurring time and availability are confirmed before payment.
What is the group size and schedule for Adh Dhahirah learners?
A group normally has five to eight compatible learners, while private tuition is one learner with one teacher. Classes usually meet twice each week, normally eight times monthly. Oman is one and a half hours behind India. The recurring time is agreed before payment, with Friday and Saturday options subject to availability.
What happens in the free Adh Dhahirah coding class?
The teacher asks about the learner's objective and observes a short ability-matched task. A child may count grouped cards, a teenager may test a safe-integer boundary, and an experienced learner may design an exact-value transport contract. The teacher then explains the suggested course, format, timing and USD fee. No tuition is charged for the first class.
