Seems like rounding while retaining one or more decimal places would need to be handled by setting precision in BigDecimal. In any case, not sure how performant that is, compared to say basic rounding to integers via Math.round(). > Add Streaming Evaluators for basic math functions > - > > Key: SOLR-10356 > URL: https://issues.apache.org/jira/browse/SOLR-10356 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level.

I haven't confirmed, but I think BigDecimal can accomplish this by setting the
scale
{code}
a.setScale(b, RoundingMode.HALF_UP)
{code}

After a quick search, it looks like there are implementations involving Math.round with additional multiplication & division, and some involving DecimalFormat, NumberFormat, or BigDecimal. So not sure if round(a,b) is worthwhile. > Add Streaming Evaluators for basic math functions > - > > Key: SOLR-10356 > URL: https://issues.apache.org/jira/browse/SOLR-10356 > Project: Solr > Issue Type: Improvement > Security Level: Public(Default Security Level.

Dennis Gove commented on SOLR-10356:
Yeah, intended for streaming expressions. So far we have the following
{code}
abs(a) // |a|
add(a,b,...,z) // a + b + ... + z
div(a,b) // a/b
mult(a,b,...,z) // a * b * ... * z
sub(a,b,...,z) // a - b - ... - z
log(a) // natural log
pow(a,b) // a^b
mod(a,b) // a % b
ceil(a) // ceiling of a
floor(a) // floor of a
{code}
I'll add these ones
{code}
coalesce(a,b,...,z) // this won't actually be specific to math, we can coalesce
on any value type
round(a)
sqrt(a)
cbrt(a) // cubed root
sin(a) // sine of a
sinh(a) // hyperbolic sine of a
asin(a) // arc sine of a
cos(a) // cosine of a
cosh(a) // hyperbolic cosine of a
acos(a) // arc cosine of a
tan(a) // tangent of a
tanh(a) // hyperbolic tangent of a
atan(a) // arc tangent of a
{code}
What were you thinking for round(a,b)?
