bigdecimal clj

(bigdecimal v)

Convert v to a java.math.BigDecimal, representing ratios as doubles

clamp clj

(clamp max-val v)

Return v, or max-val if v exceeds max-val

divide-some clj

(divide-some n div)

Zero-safe division (returns value or nil)

mean clj

(mean vs)

Return the arithmetic mean of vs, or nil if empty

median clj

(median vs)

Return the median value of vs, or nil if empty

mode clj

(mode vs)

Return the mode of vs, or a seq of values if vs are multi-modal Returns nil if no mode present (all frequencies equal)

nonzero? clj

(nonzero? v)

Is v non-nil and non-zero?

percentage clj

(percentage v total)

(percentage v total places)

What percent of total is v? Can optionally specify rounding decimal places; defaults to 2

round-bigdecimal clj

(round-bigdecimal precision v)

Round BigDecimal v to specified number of significant digits

round-places clj

(round-places places v)

Round double v to specified number of decimal places

std-dev clj

(std-dev vs)

(std-dev vs ddof)

Compute the standard deviation of vs. Divisor used is n - ddof where ddof represents 'delta degrees of freedom'. By default returns an unbiased estimate (ddof = 1). For a biased estimate, set ddof = 0

variance clj

(variance vs)

(variance vs ddof)

Compute the variance of vs. Divisor used is n - ddof where ddof represents 'delta degrees of freedom'. By default returns an unbiased estimate (ddof = 1) For a biased estimate, set ddof = 0
