Method Description COBOL Equivalent

int compareTo Compares this BigDecimal with IF PACKED-NUM1 =

(BigDecimal val) another BigDecimal PACKED-NUM2

BigDecimal add Returns a BigDecimal whose value ADD PACKED-NUM1 TO

(BigDecimal val) is (this + val), and whose scale is PACKED-NUM2 GIVING

the greater of this.scale() and PACKED-NUM3

val.scale()

BigDecimal subtract Returns a BigDecimal whose value SUBTRACT PACKED-NUM1

(BigDecimal val) is (this val), and whose scale is FROM PACKED-NUM2

the greater of this.scale() and GIVING PACKED-NUM3

val.scale()

BigDecimal multiply Returns a BigDecimal whose value MULTIPLY PACKED-NUM1 BY

(BigDecimal val) is (this * val), and whose scale is PACKED-NUM2 GIVING

the sum of this.scale() and val.scale() PACKED-NUM3

BigDecimal divide Returns a BigDecimal whose value DIVIDE PACKED-NUM1 BY

(BigDecimal val, int is (this / val), and whose scale is PACKED-NUM2 GIVING

roundingMode) the same as this.scale(). Rounding PACKED-NUM3 ROUNDED

behavior is controlled by the value
of roundingMode

BigDecimal divide Returns a BigDecimal whose value DIVIDE PACKED-NUM1 BY

(BigDecimal val, int is (this / val), and whose scale is as PACKED-NUM2 GIVING

scale, int specified by scale PACKED-NUM3 ROUNDED

roundingMode)

Lint scale Returns the scale of this BigDecimal

(BigDecimal val)

BigDecimal setScale Returns a BigDecimal whose scale MOVE PACKED-NUM1 INTO

(int scale, int is as specified. Truncated digits are PACKED-NUM2

roundingMode) evaluated based on the
