n = realmax

Description

n = realmax returns the largest finite floating-point number in IEEE double precision.

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

realmax('single') returns the largest finite floating-point number in IEEE single precision.

Examples

Find the value of the constant realmax:

ndouble = realmax
nsingle = realmax('single')
ndouble =

  1.7977e+308


nsingle =

  3.4028e+38
