Numbers

Numbers are whole numbers (10) or decimals (3.14). They can be written with ASCII or Devanagari digits, and both kinds can be mixed in one expression.

चल a = 10
चल b = ४
चल c = ३.५
छापा(a + b)
छापा(b * c)
छापा(-a)

14

-10

• Negative numbers use unary minus: -5, -x.
• A decimal needs digits on both sides of the point: 0.5, not .5.
• There is no exponent notation (1e3) and no digit separators.

Division and display

/ is always true division. Results with no fractional part are shown without a decimal point. Decimal arithmetic uses 64-bit floating point, so some results show rounding:

छापा(10 / 4)
छापा(10 / 2)
छापा(7 % 3)
छापा(0.1 + 0.2)

2.5
5
1
0.30000000000000004

Dividing by zero (with / or %) is a runtime error.

Very large numbers

Every number is a 64-bit floating-point value. Whole numbers are exact up to 9,007,199,254,740,992; beyond that results are rounded, and from 10²¹ they are shown in exponent form. A result too large to store (above about 1.8 × 10³⁰⁸) is a runtime error.

चल x = 1
साठी (i = 1; i <= 25; i = i + 1) {
    x = x * i
}
