Description

where the argument within the parentheses may be an expression. Value converters perform arithmetic translation from units of one kind to units of another. The result can then be a term in a further expression.

int(x) - returns the integer part of x.

frac(x) - returns the fractional part of x.

i(x) - returns an init-type equivalent of the argument (k-rate)

abs(x) - returns the absolute value of x.

exp(x) - returns e raised to the xth power.

log(x) - returns the natural log of x (x positive only).

log10(x) - returns the base 10 log of x (x positive only).

sqrt(x) - returns the square root of x (x non-negative).

Note that for log, log10, and sqrt the argument value is restricted.
