> and ≫ look like close relatives, but they represent different Unicode characters.
> is the ordinary GREATER-THAN SIGN. ≫ is U+226B MUCH GREATER-THAN.
As with ≪, you shouldn’t assume the Unicode name gives you one universal mathematical definition for ≫.
> vs ≫ at a Glance
| Symbol | Code point | Unicode name | Typical use |
|---|---|---|---|
| > | U+003E | GREATER-THAN SIGN | Ordinary strict ordering |
| ≫ | U+226B | MUCH GREATER-THAN | “Much larger” or a field-specific asymptotic/bounding relation |
What Does > Mean?
U+003E GREATER-THAN SIGN expresses an ordinary strict comparison.
For example:
10 > 4
says that 10 is greater than 4. Nothing about > tells you how large the gap is.
What Does ≫ Mean?
U+226B has the Unicode name MUCH GREATER-THAN.
In informal notation, it can be used when one quantity is understood to be much larger than another. But, like ≪, it also appears in more technical comparison conventions.
≫ in Vinogradov-Style Notation
If f ≪ g is being used for a Vinogradov-style upper bound, the reversed relation can be written as g ≫ f.
In that setting, ≫ isn’t merely an emphatic version of >. It’s part of a convention for comparing magnitude or growth up to an implied constant.
Can ≫ Mean “Much Larger” Instead?
Yes.
Other authors use ≫ more literally to communicate a strong difference in scale. For example, it may indicate that one term dominates another in an approximation.
There’s no conflict as long as the notation is clear—the same character can participate in different conventions in different fields.
Does ≫ Have a Fixed Threshold?
No universal threshold exists.
The symbol itself doesn’t encode a numerical ratio. A document that needs a precise relationship has to define it through formulas, assumptions, or a notation convention.
Is ≫ the Same as >>?
No.
≫ is one Unicode character: U+226B.
>> contains two U+003E GREATER-THAN SIGN characters.
Many programming languages use >> for a right-shift operation or another language-specific construct. That doesn’t make it the same character as ≫.
What About »?
» is U+00BB RIGHT-POINTING DOUBLE ANGLE QUOTATION MARK.
It can resemble ≫ in some fonts, but it’s a punctuation mark, not U+226B.
> vs ≥ Is a Different Distinction
The difference between > and ≥ is whether equality is included: x > 5 excludes 5, while x ≥ 5 includes it.
Less Than < vs ≤ and Greater Than > vs ≥ covers both the strict and inclusive forms in one comparison.
How Can You Identify the Exact Character?
Check the encoding:
- U+003E → > GREATER-THAN SIGN;
- U+226B → ≫ MUCH GREATER-THAN;
- U+003E U+003E → >>;
- U+00BB → » RIGHT-POINTING DOUBLE ANGLE QUOTATION MARK.
Which One Should You Use?
Use > for an ordinary strict greater-than comparison.
Use ≫ when the mathematical convention calls for it, and check whether that convention means “much larger,” a Vinogradov-style bound, or another defined relationship.
Use >> only when the plain-text or programming syntax specifically requires two greater-than signs.
