realmin

Smallest positive normalized floating-point number.

Syntax

y = realmin
y = realmin(X)

Description

Returns the smallest positive normalized double-precision value (≈ 2.2251e-308). With argument X of a different floating-point type, returns the corresponding value for that type.

Example

realmin                  % 2.2251e-308
