Int

toExponential

RES
let toExponential: int => string

Formats an int using exponential (scientific) notation. Returns a string representing the given value in exponential notation. Raises RangeError if digits is not in the range [0, 20] (inclusive).

RES
/* prints "7.7e+1" */
Js.log(Js.Int.toExponential(77))

toExponentialWithPrecision

RES
let toExponentialWithPrecision: (int, ~digits: int) => string

Formats an int using exponential (scientific) notation. digits specifies how many digits should appear after the decimal point. The value must be in the range [0, 20] (inclusive).

Returns a string representing the given value in exponential notation.

The output will be rounded or padded with zeroes if necessary. Raises RangeError if digits is not in the range [0, 20] (inclusive).

RES
/* prints "7.70e+1" */
Js.log(Js.Int.toExponentialWithPrecision(77, ~digits=2))

/* prints "5.68e+3" */
Js.log(Js.Int.toExponentialWithPrecision(5678, ~digits=2))

toPrecision

RES
let toPrecision: int => string

Formats an int using some fairly arbitrary rules. Returns a string representing the given value in fixed-point (usually).

toPrecision differs from toFixed in that the former will format the number with full precision, while the latter will not output any digits after the decimal point. Raises RangeError if digits is not in the range accepted by this function.

RES
/* prints "123456789" */
Js.log(Js.Int.toPrecision(123456789))

toPrecisionWithPrecision

RES
let toPrecisionWithPrecision: (int, ~digits: int) => string

Formats an int using some fairly arbitrary rules. digits specifies how many digits should appear in total. The value must between 0 and some arbitrary number that's hopefully at least larger than 20 (for Node it's 21. Why? Who knows).

Returns a string representing the given value in fixed-point or scientific notation.

The output will be rounded or padded with zeroes if necessary.

toPrecisionWithPrecision differs from toFixedWithPrecision in that the former will count all digits against the precision, while the latter will count only the digits after the decimal point. toPrecisionWithPrecision will also use scientific notation if the specified precision is less than the number of digits before the decimal point. Raises RangeError if digits is not in the range accepted by this function.

RES
/* prints "1.2e+8" */
Js.log(Js.Int.toPrecisionWithPrecision(123456789, ~digits=2))

/* prints "0.0" */
Js.log(Js.Int.toPrecisionWithPrecision(0, ~digits=2))

toString

RES
let toString: int => string

Formats an int as a string. Returns a string representing the given value in fixed-point (usually).

RES
/* prints "123456789" */
Js.log(Js.Int.toString(123456789))

toStringWithRadix

RES
let toStringWithRadix: (int, ~radix: int) => string

Formats an int as a string. radix specifies the radix base to use for the formatted number. The value must be in the range [2, 36] (inclusive). Returns a string representing the given value in fixed-point (usually). Raises RangeError if radix is not in the range [2, 36] (inclusive).

RES
/* prints "110" */
Js.log(Js.Int.toStringWithRadix(6, ~radix=2))

/* prints "deadbeef" */
Js.log(Js.Int.toStringWithRadix(3735928559, ~radix=16))

/* prints "2n9c" */
Js.log(Js.Int.toStringWithRadix(123456, ~radix=36))

toFloat

RES
let toFloat: int => float

equal

RES
let equal: (int, int) => bool

max

RES
let max: int

min

RES
let min: int
