≤ (lessthan or equal to)
The less than or equal to relational operator.
Syntax

a ≤ b

a
andb
are real numbers


u ≤ v

u
andv
are real vectors of the same dimension


A ≤ B

A
andB
are real matrices of the same size


t ≤ s

t
ands
are date or datetime structures

Description

If
a
andb
are real numbers, thena ≤ b
istrue
iffa
is less than or equal tob
. No epsilons are used. Hence, even ifa
andb
are essentially equal,a ≤ b
might befalse
. For example,sin(π) ≤ 0
might or might not betrue
. 
If
u
andv
are real vectors of the same dimension, thenu ≤ v
istrue
iff every component ofu
is less than or equal to the corresponding component ofv
. No epsilons are used. 
If
A
andB
are real matrices of the same size, thenA ≤ B
istrue
iff every entry ofA
is less than or equal to the corresponding entry ofB
. No epsilons are used. 
If
t
ands
are date or datetime structures, thent ≤ s
istrue
ifft
denotes the same or an earlier point in time thans
.
The ≤
operator is implemented by the LessThanOrEqualTo
function.
