isCloseAbsolute

isCloseAbsolute(a, b, absTolerance): boolean

Defined in: packages/core/src/number/is-close-absolute.ts:17

Tests whether two numbers are within an absolute tolerance of each other: `|a

• B| <= absTolerance`.

The only form defined at the origin, and therefore the one to reach for when the operands may straddle zero — a determinant about to be divided by, a distance about to be normalised. It needs a tolerance meaningful in the caller’s units, so it degrades once the operands are far from that scale; isCloseTo pairs it with a relative bound for that case.

Parameters

a

number

The first number to compare.

b

number

The second number to compare.

absTolerance

number

The absolute tolerance, in the operands’ own units.

Returns

boolean

true if the numbers are within absTolerance, false otherwise.
