sqrt integral type Real type square root real type
example: ABS (- 4) = 4, ABS (- 7.49) = 7.49, arctan (0) = 0.0
sin (PI) = 0.0, cos (PI) = - 1.0, frac (- 3.71) = - 0.71
int (- 3.71) = - 3.0, SQR (4) = 16, sqrt (4) = 2

2. Standard function
function identifier, self variable type, meaning result type
odd integer judgment
pred For example: odd (1000) = false PRED (2000) = 1999, succ (2000) = 2001
odd (3) = true PRED (# 39; x')=&# 39; w succ(' x')=&# 39; y'

3. Transformation function
function identifier independent variable type meaning result type
Chr byte independent variable corresponding character type
ord discrete type independent variable corresponding serial number long
round real rounding long
TRUNC real truncation rounding long
example: Chr (66) = &# 39; B' ord(' A')= 65 round (- 4.3) = - 5 TRUNC (2.88) = 2
