Problem Statement
When I checked and reproduced this issue #1339 , I found that these operators are not available in the current v2 and v3 ppl statements. But I thought it has been fixed in v2? Does anyone know what is going on? Do we need to add them to all versions?

• cosh
• sinh
• multiply (see below)
• expm1
• rint
• signum

BTW, don't we support multiplication? The following query doesn't work in v2 and v3:

source=my_test_data | eval f = x*y | fields f
