realmax

Largest positive finite floating-point number.

Syntax

y = realmax
y = realmax(X)

Description

Returns the largest finite double-precision value (≈ 1.7977e+308). With argument X of a different floating-point type, returns the corresponding value for that type. Values larger than realmax overflow to Inf.

Example

realmax                  % 1.7977e+308
