safe_exp: Safe exponential

In fb4package: 'Fish Bioenergetics 4.0' Model Implementation with High-Performance 'TMB' Backend

Safe exponential

Description

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)
suppressWarnings(safe_exp(1000))
suppressWarnings(safe_exp(-1000))
