<function>expm1</function> devuelve el equivalente a
|
|
'exp(<parameter>arg</parameter>) - 1' calculado de tal forma que no pierde precisión
|
|
incluso cuando el valor de <parameter>arg</parameter> se aproxima a cero,
|
|
un caso donde 'exp (<parameter>arg</parameter>) - 1' puede ser inexacto
|
|
debido a la resta de dos numeros que son casi iguales.
