Description

n = realmin returns the smallest positive normalized floating-point number in IEEE® double precision.

realmin('double') is the same as realmin with no arguments.

realmin('single') returns the smallest positive normalized floating-point number in IEEE single precision.

Examples

Find the value of the constant realmin:

ndouble = realmin
nsingle = realmin('single')
ndouble =
