Function isNormal

Determines whether x is a normilized number or not.

bool isNormal(F) (
  F x
)
if (isFloatingPoint!F);

Normalized number is a number that can be represented as 

 m*2e

where m is the mantissa and e is an exponent that fits into the exponent field of the type F.

0 is neither normalized nor denormalized.

Parameters

NameDescription
F Type of the floating point number.
x Floating point number.

Returns

true if x is a normilized number, false otherwise.
