Check difference and / or equality of numbers
Check if one number is greater/lower than or equal to another.
agteb(a, b) alteb(a, b) aeqb(a, b)
a |
Numerical vector of numbers |
b |
Numerical vector of numbers |
Not all numbers (especially the decimal ones) can be represented exactly in floating point arithmetic, and their arithmetic may not give the normal expected result.
Function agteb() checks if a number a is “greater than or equal to”
(gte) another number b. In the same spirit, function alteb() checks
if a number a is “lower than or equal to” (lte) another number b,
while function aeqb() checks for their equality (eq).
