math.isInf() function

math.isInf() reports whether f is an infinity, according to sign.

If sign > 0, math.isInf reports whether f is positive infinity. If sign < 0, math.isInf reports whether f is negative infinity. If sign == 0, math.isInf reports whether f is either infinity.

Function type signature

(f: float, sign: int) => bool

Parameters

f

(Required) is the value used in the evaluation.

sign

(Required) is the sign used in the eveluation.

Examples

• Test if a value is an infinity value
• Use math.isInf in map

Test if a value is an infinity value

import "math"

math.isInf(f: 2.12, sign: 3)// false

Use math.isInf in map

import "math"

data
    |> map(fn: (r) => ({r with _value: math.isInf(f: r._value, sign: 1)}))
