int
sval toExponential : int -> string
int
using exponential (scientific) notation
Returns a string
representing the given value in exponential notation
RangeError
if digits is not in the range [0, 20] (inclusive)(* prints "7.7e+1" *) let _ = Js.log @@ Js.Int.toExponential 77
val toExponentialWithPrecision : int -> digits:int -> string
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.
RangeError
if digits is not in the range [0, 20] (inclusive)(* prints "7.70e+1" *) let _ = Js.log @@ Js.Int.toExponentialWithPrecision 77 ~digits:2 (* prints "5.68e+3" *) let _ = Js.log @@ Js.Int.toExponentialWithPrecision 5678 ~digits:2
val toPrecision : int -> string
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.
RangeError
if digits is not in the range accepted by this function (what do you mean "vague"?)(* prints "123456789" *) let _ = Js.log @@ Js.Int.toPrecision 123456789
val toPrecisionWithPrecision : int -> digits:int -> string
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 for digits
before the decimal point.
RangeError
if digits is not in the range accepted by this function (what do you mean "vague"?)(* prints "1.2e+8" *) let _ = Js.log @@ Js.Int.toPrecisionWithPrecision 123456789 ~digits:2 (* prints "0.0" *) let _ = Js.log @@ Js.Int.toPrecisionWithPrecision 0 ~digits:2
val toString : int -> string
int
as a string
Returns a string
representing the given value in fixed-point (usually)
(* prints "123456789" *) let _ = Js.log @@ Js.Int.toString 123456789
val toStringWithRadix : int -> radix:int -> string
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)
RangeError
if radix is not in the range [2, 36] (inclusive)(* prints "110" *) let _ = Js.log @@ Js.Int.toStringWithRadix 6 ~radix:2 (* prints "deadbeef" *) let _ = Js.log @@ Js.Int.toStringWithRadix 3735928559 ~radix:16 (* prints "2n9c" *) let _ = Js.log @@ Js.Int.toStringWithRadix 123456 ~radix:36
