Safe exponential

Computes exp(x) with protection against overflow. Values above max_exp are clamped before exponentiation to avoid Inf.

Usage

safe_exp(x, max_exp = 700, warn = TRUE, param_name = "exponent")

Arguments

x

Numeric value or vector

max_exp

Maximum allowed exponent, default 700

warn

Logical; issue a warning when clamping occurs, default TRUE

param_name

Name used in warning messages

Value

exp(x), or exp(max_exp) for values that would overflow

Examples

safe_exp(1)
#> [1] 2.718282
suppressWarnings(safe_exp(1000))
#> [1] 1.014232e+304
suppressWarnings(safe_exp(-1000))
#> [1] 9.859677e-305
