Searching For Decimal, Percentage and Math Operators

Support for Decimals and Percentages

Searching for percentages and decimals is possible and has been made easy. PatSeer automatically takes care of spaces when searching for decimals or percentages. Further numbers attached to text (or embedded within text) are also automatically searched.

Here are the examples for searching decimals and percentages:

0.1 - matches 0.1, 0.1mm, K0.1N

.01 - matches .01, .01mm

[0.1 TO 0.3] - matches 0.1, 0.111, 0.101,..., 0.2992, 0.3

0.? - matches 0.1,…, 0.9. Will also match 0.5mm or K0.1N

9e.04 - matches 9e.04, 9e .04

"802.11g" - matches 801.11g, 802.11 g

To search for percentage character, please enclose it in double quotes.

5"%" - matches both 5% and 5 %

"5%" - same as above

0.01"%" - matches both 0.01% and 0.01 %

?"%" - matches all single digit percentages

??"%" - matches all double digit percentages

[0 TO 100]"%" - matches 0%, 1%, 2% ….. 99%, 100%

[0.4 TO 0.49]"%" - matches 0.4%, 0.40%, 0.405%, 0.41%, 0.41155%,..., 0.489%, 0.49%

[2.1 TO 2.45]"%" - matches 2.1%, 2.101%, 2.11%,…, 2.44%, 2.45%

IMP NOTE: In Range Query, you must use either integers or decimals on both sides of the TO operator. So [2.5 TO 3] may lead to a ambiguity and may not match 3.0

Additional Searchable mathematical operators

In addition to the already supported Greek characters, we have now the following mathematical operators also searchable. Please enclose them in double quotes while searching. Here is the list of the operators whose support has been added:

∑ Sum

∫ Integral

∂ Partial derivative

√ Square root

≠ Not equal to

∞ Infinity

∕ Division slash

∆ Delta

∇ Inverted Delta (Nabla/Del)

≥ Greater than or equal to

≤ Less than or equal to

≈ Approximately equal to
