Fused multiply-add

fma() computes x * y + z with a single final rounding step. This can be more accurate than evaluating multiplication and addition separately under a limited-precision context. The arguments follow normal vctrs recycling rules.

Usage

fma(x, y, z)

Arguments

x, y, z

Decimal-compatible vectors.

Value

A decimal vector.

Examples

fma(decimal("2"), decimal("3"), decimal("4"))
#> <decimal[1]>
#> [1] 10
